Mac Mail moving huge quantities of messages around after I set up a few rules

I set up a few rules to tidy up my inbox. Now Mac mail seems to be moving about huge quantities of emails and moving a steadil increasing amount into the "on my Mac" bin, including many from the last few years it would be useful to keep. I've turned off all the rules that have conditional rules to send emails from specific senders to the bin. It's pretty concerning. Any way to stop this and even better reverse it?

I'm on an M23 2022 macbook air running ventura 13.2.1

Many thanks

Phil
