How to fix the select function when using pen tool

When I use the pen tool and then do CONTROL+ENTER it selects the shape I just made with the pen tool. I then copy and paste and it creates a new layer of the selection. I've been doing this for years it works great. But...

For some odd reason now, CONTROL+ENTER selects the INVERSE of it and I have to go up to the menu and select INVERSE and then the selection is what I want. I have no idea why it does this now, so is there a way to fix this so it doesn't do this any morre?

Thanks.
