Unable to view "Change Variable Mode" icon in layer panel

It is a new fiature and it is very glitchy because of that

I’ve found that if a component doesnt want to show modes changing icon in Layer block — then I must assign at least one to the component properties, f.e. boolean to its visibility (if I dont have to hide it dynamically) then the mode icon appears.

Whats more interesting — when I clear the boolean set by variable — the set mode icon vanishes but IF I’ve chosen the mode for this component other than (Auto) — it keeps this parameter (it is seen in layers panel on the left) though there is no button in interface to change it…
