Some checkbox settings not applying

Question

When I change some Civi settings they do not get applied. It seems to be only when deselecting some checkboxes. For example, in Custom Fields I deselect: Collapse this set on initial display. It looks like its saved but when I go back to the settings it is still ticked.

I can tick: Collapse this set in Advanced Search. hit save and it stays ticked. But when I untick the box and it remains ticked.

When I deselect: Is this Custom Data Set active? - The settings are saved.

This also happens in the Edit Scheduled Reminder settings page. I untick: Record activity for automated email and hit save. When I go back into the settings for the reminder it is still ticked.

There are no obvious logs. CiviCRM 5.25.0, Drupal 7.70 , PHP 7.3.18

Have submitted fix for the issue, can you apply patch from here or you will need to wait for 5.27 release.
