Steam Livery Designer Liveries And Formation Designer Formations Does Not Appear

Found a possible bug(?). Any livery designer liveries and formation designer formations I've made since the TSW6 release does not appear in my game. Any that has been made during TSW5 or earlier and imported work fine, both formations and liveries.

Altering a livery or formation also works, but if I make a new one for that train, all of them including old ones imported from TSW5 stops working.

 

Having the same issue and have raised it with DTG Support
