Red Raw settings buggy? Need help

Does anyone else have issues with the built-in "Modify RED RAW Settings" process in FCPX? I'm running Red Apple Workflow v11 and FCPX 10.3.4. I'm trying to revert all my Raw clips to a neutral setting before color correction and my changes don't want to take and many times it gives me the error "Final Cut Pro must complete other tasks before performing this operation...The operation cannot be performed because "Calculate Render Bar" is running in the background. Use the Background Tasks window to monitor or cancel the task before trying again" ...but nothing is running in the background! Seems like a bug but I've never worked with RED footage before.

More details: I have 17 RED clips from an Epic-X in my hour-long documentary. I'm preparing to send this out for color correction at a post house. Our process is to color correct from a ProRes HQ quicktime that I export, so I need to revert all my clips to a neutral tone so our colorist has enough to work with.

Any suggestions appreciated.
