Box Cutter 719 SEAX - Inset issues

Has anyone else found that the ‘Inset’ function does not work properly? I installed Hard Ops / Box Cutter into Blender 3.2.1

I try to do an Inset, but it barely makes an indent.

I want to do an Inset / Solidify adjustment, but it does not seem to work. Am I missing something?

Thanks!

With the purple box active, or having sized it, before clicking, press TAB to “lock” it, then use ‘T’ to alter the thickness. It just may be the default thickness is super-thin. Works fine on my 3.2.1
The oddity with the flickering is multiple inset booleans getting conflicts, just shifting the inset slightly corrects it. That’s just a boolean gotcha really, which is why sometimes people apply so many booleans before doing others.
