The only way this can happen is if you've added other HR sensors to the watch. Remove all HR sensors added to the watch and add only your own.
If that doesn't help then please describe the issue in a bit more detail. When does it occur? What type of activity are you doing? Are you adding any sensors to the watch etc.
Thank you. I can’t find sensors anywhere on my watch to delete other one. It occurs when i run with him. I could have added him, but now i don’t know how to delete his.
