"Dependency file not found" Pops Up

I'm translating several ".sdlxliff"s received from a translating company.
There are no "source file" something like that - this is a kind of regular work procedure.

I've just met an irritating pup up "Dependency file not found" at my new project.
Is there any way to remove/suppress this one  ?

I have to deal with it for several days.
I do not need this pop up at all.

Thanks
