Bank was there - now it is gone!

Bank was there - now it is gone!

I added my Bank account successfully to zoho - Affinity Federal Credit Union and the automatic feed is working.  I have since opened an additional account at the bank.  When I go to add the new account the option for my bank is no longer in the list.  Is this because I already have a bank account in zoho from this bank?  Or has the list of banks been updated and my bank removed?  Thanks.
