If I create a multiinstance DB for a FB with a multiple call of another FB, and then I need to access variables from HMI, it isn't possible to drag & drop variables from DB to HMI page or variables list. If I use a single instance DB everything works. I experienced it first with a library converted from V11, but then I tried with a brand new FB/DB and I obtained the same result. Please could anybody make a test to verify if it is a general bug or only my problem? Thank you

I think for instance DBs the visible in hmi default to no.
