I have setup my scrub task like that (since months)
but recently something not working as expected: every scrub task lunch, perform scrub on all pools, ignoring thresholds days.
Yesterday multi report:
Today multi report:
looking behind on multi report, i see that something is starting going weird since fresh install → upload config after mainboard change.

I do not see a similar situation on my CORE system.
Something i can try, or any other tips (Before opening a bug report/issue).
Check your scrub schedule, if there is nothing strange do a clean install.
As you can see, nothing strange for me, configuration is pretty minimal from gui. Don’t know if i can access more info from shell (for example).
If a clean install is the only option i will try it those days
Scrubs are ignoring threshold days on my system, running
TrueNAS-13.3-RELEASE. Scrubs are set to run Sunday on one pool, and Mondays on the other, with a threshold of 10, so that they run every second week. Since I upgraded to
TrueNAS-13.3-RELEASE they are running every week.
I have disabled them, still didn’t have had time to perform a clean install.
Have you try something?
Edit: opened ticket
Create a bug report.
Seems the problem has been quickly fixed.
But don’t know when we can enable scrubs again 
In the end I applied the small patch manually.
File is
/usr/local/lib/python3.9/site-packages/middlewared/plugins/pool.py
line 46:
change
RE_HISTORY_ZPOOL_SCRUB_CREATE = re.compile(r’^([0-9.:-]{19})\s+zpool (scrub|create)’
to
RE_HISTORY_ZPOOL_SCRUB_CREATE = re.compile(r’^([0-9.:-]{19})\s+(py-libzfs: )?zpool (scrub|create)’
you did good, 13.u2 will be never released anymore
