Fluid Motion and Steady Video options are not displayed under Triple Monitor

I am using the R9 390X in a triple monitor environment. I wanted to try Fluid Motion and changed the video profile to custom to display options, but they will not be displayed.




I tried reinstalling the driver, trying to reduce the number of monitors, and found that the items are displayed properly only when the number of monitors is 2 or less.




Is it possible to use Fluid Motion under the triple monitor?
