Gap in Bottom Corner of Aluminium Bifold Doors Allowing Draughts

[WILLShorty]

Hi, I had aluminium bifold doors fitted in my property when I bought the house about a year ago, I haven't got around to completing the room until recently and I just noticed there is a draught coming through the new doors and when looking closer at this realised that there is a significant gap at the bottom right of the closing door (and frame) roughly 6mm and the seal is not touching however the top of the doors and the other 2 panels are sealed well. I haven't tried any adjustments as of yet because I don't know much about these type of things but I was hoping someone could point me in the right direction of how to fix this problem ?

Don't attempt to do this yourself, you will need to contact a specialist,
