Scenario Designer Not Working In Scenario Designer/timetable (xbox)

I have created a livery on the class 377/4 SN but when I go to use the livery in scenario designer It doesn't show that I have any reskins of the vehicle

 

There is currently an issue with the livery designer for the class 377. I believe DTG are aware of it as it is affecting all platforms.

 

Is it Only the 377?

 

Because I also had an issue with the 72 Stock and I know It's working on PC

 

I'm not sure about the 72 stock. I think there were reports a while ago that custom liveries weren't showing up in scenarios or timetable mode (possibly December or January).

 

Ok but what should I do about it?

 

Currently there's nothing you can do about it. DTG are aware of the issues and will hopefully be working on a patch/fix for these issues.
