Why can't I see a value in the slicer that I can see in the filters bar?

I have this situation in which I am trying to look for an object from a slicer, but I can't find it. The only filter applied on the slicer is a "Year not blank" that I made sure wasn't the case. When I look for it in the filters bar, though, I do find the object I am looking for.

The model is quite complicated in its entirety, but the way this table containing all the info about the projects is linked to the facts table is through a 1 to many relationship. 

Does anyone have any idea? Thank you

hard to tell without seeing your implementation. Can you prepare a small sample pbix that demonstrates the issue?
