How to *properly* delete a policy?

Hi. I recently made some changes to my system, I moved everything from $HOME/a/b/ to $HOME/a/ effectively removing the b directory)

So I had to delete the policy for $HOME/a/b and make a new one for $HOME/a

To delete the policy, I simply click on Edit and then Delete Policy

Going to the Snapshots page, now I see the both the new snapshot and the old snapshots
But for both directories (which basically have the same policies, just different path) it shows “Next Snapshot in 5 days”. Even for the deleted policy.
(see my reply below because I cannot add more than 1 picture)

Note that two days ago already tried making a snapshot (with 0B) since that folder is now empty.

How can I stop automatic snapshots of the old directory?
