I'm adding a cube to my scene and then hitting Ctrl+4 to subdivide it 4 times. However, it only subdivides it 2 times (Blender 3.5 and 3.6). After some experimentation, I have discovered that using Ctrl+1 and Ctrl+2 both work as they should, but Ctrl+3 and Ctrl+4 seem to be capped at 2 subdivisions.
Also, if I apply the modifiers, they only subdivide to level 2. Any idea what's going on?
