s2Drip from_day not working?

I am a Pro member. I have this code:
[s2Drip access=“level1 AND ccap_level3mns” from_day=“31”]link[/s2Drip]

When I log in as this user (with s2Member Level 1 role and custom capability “level3mns”) who registered on Mar 16, 2022 with no EOT, I would expect to see the link (today is Dec 16, 2022) since it is definitely more than 31 days since he registered. But I do not see it.

Help please.
