Export Revisions to Final Draft (FDX)

Hello there,
I have a Scrivener document with FOUR revisions in FOUR DIFFERENT COLORS. I compiled it for Final Draft (FDX) and I didn’t choose to “remove colors” in the Transformations tab. Yet, my Final Draft document shows ALL MY FOUR REVISIONS in one color. I mean, the Final Draft document has “condensed” all my four Scrivener revisions in only ONE REVISION (First Revision in Final Draft): is there a way to compile to FDX leaving four revisions in four revision colors in the FDX document?
PS. I work with a Mac, I have the latest version of Scrivener and Final Draft 8.0.3.1.
Hope you can help,
Francesco
