Unable to Add Vertices to Surface in Action

So, this is a new one. When I go to action, select a surface, change to bilinear, and try to add vertices, I can’t. It’s greyed out. Same with extended bicubic. Any surface, any action, any project. Running 2026.2. Gotta be something dumb on any end, but can’t figure it out. Any ideas?

Try turning “Autokey” on?

I always have it on. Tried turning it off, but that doesn’t change anything.

Yeah, it’s something dumb. I don’t know what I was doing. But it works fine. Extended bicubic should have been my first clue. Don’t know why I was trying to add vertices to a bilinear.
