Enter command does not seem to be working for Solid Pipe

Hello, as the title says, I am trying to use the solid pipe (I’ve tried with both the flat and round caps) and for some reason, the end command is not working. The solid that was in progress is just deleted, as if I had pressed the right click. Enter seems to work with other functions, though, and it had worked just yesterday. And I know that I did not actually create a solid because there is no solid creation in the undo multiple list.
Not sure if I changed any of the settings, but I’m pretty new to Rhino.

It seems to work correctly here. Is this with any curve, any file, or one in particular?
