Two Onedrive folders in Explorer

I'm having the "two Onedrive folders" problem but it seems different from any of the ones I've seen posted. Brand new HP, I was setting things up and downloaded/installed Onedrive. (This may be the root of the problem, I now see that Win 11 does this automatically.) I am now seeing my Onedrive folders twice in File Explorer. They are exactly the same, and if i change one, the other changes immediately. They are both labeled Robert-Personal. I have seen suggestions of unlinking my Onedrive account and relinking (how do I do this?) or editing the registry (Scary, also, how do I know which one to remove?). Please advise!
