Create Child actor based on master BP is not working

I created a master bp for my game which consists of three wall meshes, and one floor. I compiled it. Saved it, and went back to the content browser. I am trying to create a random dungeon generator based on the master bp. I right-click the master bp, go to asset actions, and the option to “create child based on this” is grayed out. It was working fine last night. Anyone know what may have caused this to happen?

You can’t see it here?


That is exactly what I did. But, the option is grayed out and unclickable.

I also attempted creating a new project, thinking maybe my original project had a bug, but it is doing the same thing in the new project.


You are actually clicking on the wrong area to create a child blueprint. See my screenshot attached.
