$100 Credit for Transaction

I’ve been using Stessa for 2+ years and have had a particular bank account synced to Stessa for over a year. It’s worked great. Recently, at the start of 2021, this particular bank account is adding an extra $100 credit transaction for every legitimate transaction. I have no idea why.

Every time I have a legit transaction, a $100 credit is automatically created. This just started in 2021. Any ideas? Thanks much.
