Functional Exchanges not visible

Hi all
I have a highly fragmented model.
I am now creating functional exchanges between functions in different components (logical architecture) and when I try to allocate them to the corresponding component exchange I can’t see any functional exchange on the left side of the selection panel. Any idea why this could be happening?
This issue is severely hampering my progress…
Thanks
Ricardo

Even though working with fragment can be a burden, I would be surprised if it had impacts on what is proposed on the left side of the selection panel.
Are you able to reproduce the problem on a sample model, fragmented or not?
Does the problem disappear when you close / restart Capella?
