AFAIK, there are still some doubts whether 14b vs 16b modes are handled properly on the GFX series, but that should be resolved soon (by dt 4.4 most likely). Were you shooting these and creating the profile at 14b?
Also, what version of the tool are you using? There was a problem with it before (please make use of the forum search facility), but should be ok from dt 4.2 and on master today…
