So my nephew borrowed my watch a few months ago and since he's a lot younger his max HR was about 208. My max is like 191 and after every run my forerunner keeps detecting a new high HR. I've manually adjusted my max HR a couple of times and deleted the activity of my nephew both on garmin connect and on the forerunner itself. Still it keeps detecting a new max HR. I like to keep my HR settings on auto detect. How can I fix this?
