Steam Tsw 6 Wcml Preston - Carlisle . Class 87 No Longer Showing In Timetable Mode

This is a weird one,
Since updating to TSW 6 ,Just Trains WCML Preston to Carlisle , The Class 87 no longer appears ( ie no picture) to select in timetable mode.
It still works in Scenarios & training .
I have reinstalled it & verified the files ,but it still does not appear in timetable mode.
I have had this DLC since it was released with no problems until TSW 6 update.
All the other stock & layers are there.
I'm on windows 11.
Can't think what else to try.

 

It appears to be " Spirit of steam " DLC that caused the issue.
I brought " Spirit of Steam " in the Autumn sale last week as it was so cheap, so I uninstalled it & the Class 87 reappeared in WCML Preston timetable.
Reinstalled Spirit of Steam & Class 87 no longer shows up in timetable WCML Preston.
