It is probably my fault but here’s the story. I used Anki a lot in 2016-2018 and then stopped, last week dug out the old deck I was using and I cleared it out of history and imported it to a clean account (deleted and created anew for the same e-mail address).
I used: “export without scheduling” option before importing it to my new account anew.
ad 1) Cool, thanks!
ad 2) Mine is 2.1.39 at the moment. I’ve exported the deck just a couple of days ago and earlier my deck was lying around the Anki server. So I guess it should be fine but maybe I’ve done so many things/steps that I don’t remember anymore :(.
I applied your execute on the mw.col and now the statistics seem alright:). Thanks!
