Aple watch, latest watchOS, annoying green call dot on top

Hi, watchOS is 8.1, the latest one, everything was just fine for weeks, and 7 days ago this is happening after every call. Reset does not work. This is annoying, and really really annoying. This bug was present last year, and now again. Why it really bothers, because after each call, no metter answered on watch or iphone, it is present. You have to tap the dot and quickly cancel the call, not to call someone incidently. What is the solution?
