A couple of things. Please read the Read Me Before Posting sticky post at the top of the PD17 forum and follow the instructions for running and attaching the DxDiag results along with the exact PD17 version number. Sometimes problems like this are caused by outdated drivers or system configuration problems.
When you say you see the LUT changes on the timeline and "also in the Produce screen," does that mean you have this box checked?
That should be a direct read off of the output stream, and I can't imagine you'd see the CLUT effect there but not in the produced clip. If that's what's actually happening, maybe you could upload the original clip, the LUT you applied, and the produced clip to a cloud sharing service and post the link here for others to test out.
Use Google/Bing to search for CLUT .cube conversion. There are apparently two completely different and incompatible types of .cube LUTs, but I believe you'll be able to convert the incompatible ones to one of the supported PD
formats.
