PC I Can't Use My Own Livery

I made a livery for BR 406. But when I'm trying to use it in timetable mode, I can see only the original ICE3M.

 

There is a post on the announcements forum addressing this issue. I actually came to the forums to post a similar thread as you, but DTG JD made a post saying that the issue was caused by the most recent patch and they are working on a fix
