Lactate Threshold not auto updating

I have a F265S and a HRM Pro Plus chest strap. My understanding is the lactate threshold should update automatically with workouts but this hasn't updated at all. I run 5-6 times a week so would think it should have updated my threshold pace, just finished a 25km run with avg 4:49 pace, with the last 10km being 4:36 pace. Also ran a 15km a couple of weeks ago in 1:05:27 (4:22 pace). Surely that would mean by LT pace is closer to 4:22?

it's a good point, I reset everything to use max heart rate (including the coaching recommendations rather than pace). It gives much better suggestions and then also leave the watch to auto update max heart rate and threshold. I lowered the max heart rate and did a guided lactate threshold test which just hurt and then failed to find my threshold..aaargh. So I lowered a few more beats, did a running session with some fast intervals (not a steady run) and got an update straight away. The max. heart rate wasn't changed just the threshold
