creative colours missing

Hey all, I am working on a music video and today when I opened Premier, the project was missing from the opening screen, I found it on my t7 but all of the colouring has gone, all shots should be with the SL NOIR LDR, colouring, the program says it's on but the picture is in colour, my client does not want colour and this is a big thing.  I have tried to take off the filter then re apply it, but that didn't help, it changed nothing.  How do I fix this?
