What is "Disable logging" option in System menu?

In my Venu 3 (fw 6.21), I see "Disable logging" option in System menu, last after Information option.

Problem is, after I Disable it (should I?) it comes back after some time allowing me to again disable it.

Any ideas what is that and what do I do with it?

EDIT: I did a restart of watch and it didn't appear since. False alarm maybe?

EDIT2: After restarting watch, it reappeared after some time, still allowing me to disable. I'm still waiting for 6.22
