FBX animation from Blender 2.8 not importing correctly



I am using Blender 2.8 to export an FBX animation for use in Studio. I have a perfect swim cycle of a fish set up in Blender. But in studio the end frame changes, ruining the cycle. It seems to cut off several frames. You can see this in the attached image. I have been able to work around this by adding static key frames at the end in Blender but the amount is random and is just a band-aid. I have uploaded the FBX file to SketchFab and imported into Studio and it works fine but the file is bigger and this is an extra step that I should not need to do. The Studio documentation is for an older version of Blender. Any ideas?
Thank you so much for your help!
