This is clearly a software bug. I've been putting up with it for nearly a year now.
Same 'solution' works for me:
1. Go to Rules. Open a rule to edit but simply resave the rule without any changes.
2. All Rules will be applied to the bank feed and all transactions with a rule will be categorised.
It's a shame Quickbooks has let this go on for so long.
