Description

I noticed that, in some cases, when the list of probes is displayed downward, the save bar overlaps this menu, which can be quite inconvenient for selecting the different probes.

Fixes #(issue)
I have therefore made sure that this menu no longer overlaps the list.

Thanks for the contribution (seems like a simple enough fix to include even this late in the cycle) 👍🏻
