Template leased-tag quality bug?

i reference a tag (leased mode scan class) by an expression like
tag({Blablabla}+"/Blablabla").

the label showing the tag value is in good status only when i’m inside the template designer containing it.
when i see it outside the template editing window (both in a designer window or in the client) the same label shows a bad status.
:scratch:
any suggestion?
