Midi Connections Get mixed up when Changing Between Projects

Cubase 8.0.35, windows 10

Open First Project (activated by default) [11 vienna ensemble connections]
Open Second Project [Roughly same midi setup]
Activate Second Project
Activate First Project

Midi connections in first project don’t ‘remember’ - that is all the midi instrument and channel listings show up in the inspector but some (not all) of the instruments are routed to the wrong midi instruments and channels.
