Cisco Catalyst "version changed" flapping

For some of our Cisco Catalyst 3850 series switches, I'm seeing regular "version changed" flaps in the event log, but nothing has changed on the switches.

Examples:

2022-07-07 23:35:02 Version changed: 'Gibraltar 16.12.07' -> '16.12.7'

2022-07-07 23:30:31 Version changed: 'Gibraltar 16.12.07' -> '16.12.7'

2022-07-07 23:10:44 Version changed: '16.12.7' -> 'Gibraltar 16.12.07'

2022-06-30 22:20:09 Version changed: 'Gibraltar 16.12.07' -> '16.12.7'

Also seeing it for switches running 16.12.3a

I don't think it's a problem pe se, it's just confusing (and possibly giving misleading info to managers regarding our sofware update progress). Do you have any idea what's causing it?

Many thanks!
