Save bloc and bric (SOLVED)

I have made a team slider with the carousel bric … Now I want to use it on other pages as well …
But when I save the Bloc to the library and use it in a new project the carousel looks different …
some classes missing. ( for example carousel caption etc ) But they are not. shown when saving the bloc ? Any ideas for me that I have not create all from scratch :frowning:

thanks tom

Update: Saved some classes in the custom class section - now it works
