Can't edit hide volume area- stays red and disappears

Describe the Bug
Items were put in hide volume area and then i added a different one and it left the first one. When i click edit i cant adjust it, even after restarting the program and reloading the map.

To Reproduce
not sure if i can. I’ve tried copy pasting the area back on top of itself, and tried doing another hide volume on top and changing it all to visible but then it disappears.
