XYplorer Beta Club

I dont know how to reproduce this, but sometimes i see one or more of my tabs having secondary sort even though I have not done it in past 4 days or so.
It could be that some pattern of clicking within or between tabs is triggering this tiny bug.
Just reporting so that others keep an eye on this too.

Happened again, primary sort on created (big triangle) and secondary sort on name (small triangle).
Anybody noticed this?
But I still cannot reproduce it.

I saw this too very few times. No pattern recognized so far.
