Error when trying to categorize bank transactions

Error when trying to categorize bank transactions

I am trying to categorize my bank transactions.  It was going fine, I categorized 50 or so transaction and suddenly I started getting an error that reads:

"Transactions cannot be matched as the account you are trying to match it to, is different.".

I select a transaction on the left, and Zoho brings up possible matches on the right.  The one on the right is clearly the correct transaction, so I select Match and I get this error.  The weird thing is it will sometimes works (but rarely).  I have no idea what this error means or why I am getting it.  I haven't ever seen this before and nothing on my end has changed to cause this.

Can someone tell me what this is?
