Intermittent problems with VS using Cessna 172 standard

Not only that, I also noticed a conflict with the Nav function. When setting altitude and then engaging VS, the plane also reacts by banking in whatever direction for some reason, as if U have Nav engaged. There are no conflicting binds from what I can see.
PS- as suggested, I sent a query to the Honeycomb helpdesk today- provided them with my current MSFS settings. Hopefully they can provide some feedback as well.
