Unreal Insights Stats Trace missing

Hey guys,
I’m trying to profile my game with Unreal Insights, and I noticed that the Stats Channel can be enabled.
I enabled it, but the stats don’t get included in the trace file. I mean, I can see the list but they are empty, as they haven’t been traced at all, their value is 0 for every frame (see image below).

I also noticed that some stats actually get traced correctly (but only few of them).

Am I doing something wrong?
