New Command bar using PowerFx gives error "The Component Library is still publishing. Please try again."

[gv-booost]

I have added a new dropdown in a command bar, on which I have put two buttons, both having a PowerFx formula. The first button does nicely what it should (patch statement), but the second one, regardless of the function (e.g. Notify or else), remains giving the error  "The Component Library is still publishing. Please try again.". Waited for days, republished, recreated it and no change in behaviour.

But then I switched the two buttons on the dropdown, published it and the second button (now on top) works! But wait: the first button (now at the bottom) should be failing, right? NOT! It was working, too! Switched them back, and no problem whatsoever!

So if this solution helps you please mark it as such! Thx! 😀
