I am using QB DESKTOP for a MAC 2019

I am trying to edit a couple of accounts in the chart of accounts.  One of them is 401(K) Payable.  By mistake I coded it as accounts payable.  It should be a liability?  When I go to chart of accounts>401(K) Payable>edit-upon saying- I get an error message saying that "you cannot change an account type to or from an A/R or A/P".   

In QB you cannot make an honest mistake?  There are no entries as of yet.  Why can't I make the change?
