Glad I could help.

Here's what I suspect happened: Normally, [return] is translated to "\r"
(RET), but on a GUI Emacs it's possible for them to have separate
bindings.

You (either in your own configuration or in a mode you use) likely have
a binding for [return], which causes it not to be translated to "\r".
The popup package only creates a binding for "\r", so your [return]
wasn't triggering it. On the other hand, [kp-enter] did not have its own
bindings, so it was translated to "\r" and thus worked.
