Hi,  
My anki collection has lots of cards already, but I wanted to add another deck.  
However, when I try to add this deck, I get the following error:

Import failed. Debugging info:  
Traceback (most recent call last):

anki.rsbackend.InvalidInput: InvalidInput { info: “attempt to save stale notetype” }

If I add the same deck to an empty new anki profile, there are no problems. So I am assuming something is conflicting with the currenty profile / cards I have.  
Can you help me figure out what may be wrong?  
Thank you.
