Lactate threshold data mix with running and cycling

I have a FR645 and an EDGE530, one for running (with chest strap) and one for cycling (chest strap and power meter).

Lactate threshold data are completely mixed together in the ANDROID APP:

As you can see, data with also a blue dot are running data (because they have pace) and data without it are cycling data.

This creates a weird graph, and my last lactate threshold value is wrong: 169BPM is my cycling threshold, not my running threshold, so 4:46 pace is associated with the wrong BPM.

In fact, the data are taken from both activities and only last available are displayed in the current lactate threshold reference.

My FR645 stil shows me my last "correct" running lactate threshold:

In Garmin Connect web site the situation is even worst: the graph does not allow you to recognise the difference between running and cycling "data" and cycling data are used in the running section (Corsa, in italian):

There is no lactate threshold report under cycling section nor in the "all activities" section, so as user I supposed that running section should contains only running data... but no.

Small update, I've tried to disable lactate threshold BPM auto-calculation in my EGDE530, but after a ride another meaningless 169BPM point was added to the graph, associating it with my latest running threshold pace.

Small Addition:

I only have the 530 with power and HR (My 920XT does not provide Lactate data). For me both the Android App as well as the Webpage say "No data".

So it seems to be taken from both in your case but only provided if running is available.

Today I've checked again the situation and now it's solved, in both Garmin Connect web and Android APP. Now my anaerobic threshold graph shows only my running data, so the graph is meaningful. Thanks Garmin!

not here, always mixing between running FR945 and cycling Edge 830

Fantastic, did you do anything else except disable auto calculation?

I have just a fenix 5+, so either I disable LT detection for both cycling and running, or keep them both. And of course both GC app IOS and GC web are mixing them. The only way to “solve” it is the deletion of cycling HR zones and just using a universal HR zones. Which is not a solution, indeed.
