Practice Assistant deleting Stats

Hi everyone, I tried searching this forum but no one seems to have the same problem, so I am probably doing something wrong :smiley: I just started 2,5 weeks ago and I really like the practice assistant, but it seemingly deleted my stats. (Changing the dates it still only shows the last 3 days.)

So after finishing a Module, I archived the individual items and deleted the (now empty) practice routine, which apparently also deleted the stats. So I am not sure how to use the assistant, keep every item and every routine? will archiving the individual items delete the stats or only if I delete the whole Routine. I hope I explained clearly.

Thank you for any help and thank you to Justin and all the team for helping people learn.
