Extrude "greyed out" when attempting to add it to Modifier Set in 3ds Max

[foofoo]

Hi, Im not the most technical but know the basics of Max and recently when I set up the to configure the modifier sets "Extrude" is greyed out and I cant activate it ...as i used to use this a fair bit with my low poly modelling or at least i think i did....can any one remind me what im doing wrong?

thanks

What type of object was selected (was there more than one) when you asked for the list of modifiers

just from a clean scene, create a cube...go to modify and extrude is there but greyed out and does nothing....im assuming i`ve done something  silly but cant figure it out.....annoying as extrude is one of my go to`s in modelling

You can extrude linear object like lines, splines, arcs, etc. but not 3D objects. If you have a 3D object such as an Editable Poly, select Polygon  subobject and the extrude option.

When I go to the modifier sets I also cannot click Extrude.  Also I have a blank box in the middle somewhere, and when I add a new box (from 23 to 24) it gets created underneath box 23.   Like... half and half.  Looks like a bug to me.  Tested on 2024.

But, the right click menu works for it which is faster I guess.  Right now it does seem bugged but that's a potential workaround.
