My advise would be, try again. If Opencpn is getting position data, NMEA multiplexer should get data too. Delete the serial connection in Opencpn and create it on NMEA multiplexer again. If you have already obtained position, that will be a 'hot start' and you should get position in Inspector after few seconds with a clear view of sky. With no errors in debug mode I think it could be a coincidence between your two tests.
If you are starting a GPS for the first time, or after it has been powered off for more than a few weeks, this is a 'cold start'; it needs to get a new satellite almanac to do its job. The satellites broadcast this information very slowly (at 50bps) on a fixed schedule, and it can take up to 20 minutes.
