SWbug: not synchron coach week clock vs app

This topic is reported a couple of times and Garmin is not ablt to understand? Why?

SW Garmin Conect App, SW 5.27.0.15
My Clock: Forerunner 165, SW 28.05 latest

On the Clock: even one week higher than in APP version.
But the trainings (all of them!) are 1:1 syncronized - so that works!

Please solve this issue. It might be on other Garmin clocks too.
