100% agree.  This appeared to be fixed for a period then reared its ugly head again. 

It's so frustrating when it creates more suppliers, I had a nice clean supplier list and now it wants to add every single thing it sees on a credit card transaction.  Why would I want "Tim Hortons" recorded as a supplier?  Why did anyone think this was a useful feature in the first place?  You know it's dumb when it created a supplier named "ANNUAL FEE".  Developers, please just leave things alone sometimes, whatever is in your brain as a good idea, think twice about it.
