zone selection via midi

sometimes zone selection via midi doesnt work.
this comes randomly. sometimes some patches in one instance of halion5 this doesnt work while it does in other patches. closing the project and opening it again shuffles the affected patches around randomly so one patch might work again but switching patch in same slot can make the function go away again.
this might only affect patches originally created in halion3 and then imported (many of my banks are such and ive also found other indication of imported patches being “corrupted” somehow ie quick controls behaing in an unexpected way and becoming activated - to much frustration- when shuffling patches around)

im i alone with is?
has anyone found a workaround?
