Driver Control Centre

When I have made new sessions, the driver control centre has assigned drivers to random pieces of rolling stock, and drivers that show up showing no assigned location. The little eye is greyed out on these characters. I thought the session was corrupted somehow, deleted it and started another same outcome. Sort of confused as to why, but went an unassigned all the drivers to rolling stock, and with no location. Never used to happen but maybe its a little bug in the system somewhere.
