I feel like my galaxy watch ultra heart rate sensor is reading wrong.

My galaxy watch 4 never looked like this. My heart rate would go up and down accordingly. About 15 minutes into my run something happens with my galaxy watch ultra. It's been like this for a few months. It's almost like it's reading 20bpm lower than it should be.

I love the watch in every other way. But this does bother me. I almost sprinted the last .5 miles. My heart rate definitely should have been higher.
