Workspaces mess up after closing and opening song

A song created in 7.5.2 was opened in 8.0. All the workspaces gone. I created new workspaces and saved that song from within Cubase 8. After opening the song again in 8.0 all the workspaces I created gone again it added workspaces by itself with instruments that are not in the song itself.
What is going on with these workspaces, before it wasn’t perfect but at least the user had good control but now the software creates by itself.

Workspaces in Cubase 8 is no improvement and buggy or with at least not expected behaviour.
