Lactate Threshold constantly wrong in Garmin Connect but correct on watch?!

I did the lactate Threshold guided test and accepted the new threshold of 163 BPM. The Forerunner 935 watch is updated correctly in my user profile - heart rate settings on the watch. Garmin connect seemed to update as well. For some reason now when I sync another activity Garmin connect shows my lactate Threshold as 45 BPM while my watch still has the correct 163 BPM value.

Where the heck is this other value coming from? This makes the lactate Threshold chart look pretty crazy and is frustrating! There is nowhere else on my watch this is stored
