Series X Layers Not Loading On Journey Mode

Whenever I seem to do Journey mode on a route the added Loco layers on Series X don't seem to load in (no matter if it's Timetable or Scenario). It was previously happening on Munich Augsburg and now seems to be happening on BML too. Has anybody else had this issue?

 

I just got it working by doing that work around, thanks! Really should load first time though!
