Bi-Fold Doors that are now catching on the top runner, whilst glazing is being installed.... aaarrrggghhhh!

Hello there

I've got a really annoying problem with some bi-fold doors that I have fitted. I'm at the finishing stage of fitting the glazing, and it's not quite going to plan. The frame and doors were fitted just fine, as far as I can tell. The doors opened and shut really smoothly. Looking from the inside, the doors open from Left to Right.

I fitted the first piece of glass, in the door furthest away from the main traffic opener. In picture 1 which I've hopefully uploaded successfully, this is the door to the right. I have scribbled in, in red, the corners where I have placed the packers.

After fitting the glazing in the first door and fitting the beading back in (which was really tight and tricky to get back in!), I opened all the doors to test them, and they opened and closed just fine.

I then repeated the process with the middle door, and again, Picture 1 shows where the packers have been fitted. Again, I opened and closed the doors, and they all ran pretty smoothly.

At this point, I realised that I hadn't really secured the bi-fold frame properly into the timber frame of the building that I'm building. It was secure along the bottom and relatively secure up the sides, but nothing along the top.

I had watched another video from a professional outfit that showed that you should introduce some packers at the side hinges between the frame and the timber frame itself, and screw through these to make the frame really secure. I've introduced packers behind the sides of the frame where the main door hinges are, and screwed through them to secure the frame. I've also pushed some packers into the gaps between the top of the frame and the timber itself (but these have not been screwed into place yet), as I happened to test the doors again before doing so, and found that the top roller, between Door 1 (the main traffic door), and the middle door, was now catching on the top of the aluminium frame and causing it to slide badly.

As can be seen in the two additional pictures, it's scratching/catching the top edge of the frame.

I am trying to work out if me adding in packers and screwing the sides of the frame is the cause of this, or whether I've not got the glazing packing correct?

From watching online videos - heeling and toeing errors seem to make the doors catch at the bottom, rather than at the top like they are on mine... I would be very grateful indeed if anyone could point me in the right direction of how to cure this?

Many thanks in advance for any replies.

Picture 1 shows where I have packed the glazing in the two leaf's that have been glazed, with the red L-shapes in the corners. The red line along the top shows there the top roller is catching the inner edge of the top of the frame.

Picture 2 shows where the top roller has been catching and scratching the inner edge of the frame, and the orange circle shows the top roller/bogey that is catching

Picture 3 shows the catch/scratch more closely.

All of the videos that I can find, show how where a bi-fold door seems to "drop" which is usually due to incorrect or not heeling/toeing the doors properly, that the leaf's then catch at the bottom when you try to open them - not at the top, or they show how the main traffic door lock won't operate properly, or how the main traffic door won't open properly and again catches at the bottom. I can find nothing that even describes how to adjust the doors when they are catching at the top!
