Mutable - Remove Mesh Blocks on multiple udims

I’m trying to use the remove mesh blocks on a skeletal mesh that has multiple udims, in this particular case I need to remove elements from udim 1013, and it is showing up above the allowed grid, like in the related picture. I can’t find any way to move the grid so that I can put blocks on the mesh. Is this due to an incorrect unwrapping workflow, or is it just a limitation from mutable that we have to accept?
