Running out of space in the Interactions Tab

Does anyone else have this issue where the interactions tab essentially runs out of space?

I’m only at 50%, but as you can see in the images it only lets me add another interaction at 51%, then 100% and I can’t add one in between.

I’ve tried increasing the height of the section but that has no impact.

Any ideas?
