Problems with Renaming Cards+issues

When I tried to create a cardtype for a name that I had used before, then renamed it failed without any error.  I created a Cardtype card called "Transaction", then renamed it "Purchase Transaction".  Now I try to create a new "Transaction" and it just doesn't do it (no change in screen).  If I go to the Transactions card and try to remove it, if offers to remove "Purchase Transactions" (not what I want).
