Duplicate notifications

I'm sorry for my English. I will try to explain the problem I encountered after switching from the iphone 15 pro to the Samsung S25+ using my Garmin intstinct 3 45 Solar. The problem is as follows: I noticed that notifications are duplicated very often. For example, my friend wrote me a message: "smiley face", "When will you sell?", and then on top of this message it says "When will you sell" again. It's really starting to get annoying. I also noticed that if you don't read notifications from your phone for a long time, they come back to your watch, although notification replay

is turned off. Can you tell me what to do?
