A couple of minutes after I finish an activity, the watch will suddenly show a random data screen/map

Alright, I guess this is a strange one. It first happened after the update to 13.24, never saw something similar before:

When I have finished an activity and I am back on the watchface, have closed everything down, every now and then the watch would (after sitting there for a couple of minutes) show a data screen or the map at a later point (maybe it is the last screen that I have used in the activity? Not sure). This has even happened multiple times (like twice or three times) after one activity.

It only happens within maybe 10 minutes after an activity. Otherwise everything is normal.

Not a big one, but I am wondering if this is just me or if anyone else hat witnessed this strange behaviour after going to 13.24 (and now 14.52). Or maybe someone has a solution? I have already hard-resetted the watch, didn't help.

Thanks in advance!
