Nuendo 10 + Dolby Atmos production suite


I am using Nuendo 10.2.10 & Dolby atmos production suite 3.4.0, I am encountering an issue like in the multi-panner window, sometimes even after a successful connection between both the softwares, the Object Bus Tab beside the RMU menu goes blank. Means even after selecting the dedicated object channels they sometimes get reset and i can’t find any created object channel in there. Does anyone here has experienced it? I have to connect again and again in the “Object Mode” the specific channels.
