MIDI Routing bug?

I need to do more testing on this but it’s happened multiple times so far. When I’m doing some MIDI routing, such as selecting an OUT on a MIDI track to go to the IN of a VST track, along the way my tracks mute themselves. Additionally, some tracks for the INs and OUTs in the routing, don’t display the correct name. For example, I may have a track called “Snare” and another as “Kick” and Nuendo will only list one of those by their name and the other by the default VST name.

Anyway, I may file this report more formally later. Anyone else coming across problems like this?
