UPVC double door not sealing fully

Hi, I'm sure this is a common question but I wasn't able to find the exact same one asked before.

We have a double UPVC door in our conservatory:

The seals are fine pretty much the whole way around, but in the bottom, where the two doors meet, the active door does not seal to the frame properly:

I have already adjusted the latches so that they are as tight as possible:


But it doesn't seem to have improved it at all.

Is there anything else I can do here like adjusting the hinges, or is the door just knackered?

I would start with adjusting the shootbolt keeps at the top and bottom of the frame that the slave door locks into, if you can pull the slave closer into the frame it'll allow the master to close further in, once you've done that see where the master door closes, if you haven't already then adjust the cams on the master door for greater compression and see where that takes you
