Speed changes lost after Re-conform

Version 15.0.0B.043
macOS High Sierra 10.3.4 (17E202)

After applying speed changes and retime curves to clips (dailies - QT ProRes 422LT in our case) during the offline edit, the speed changes are lost after re-conforming to the camera original footage (.cine and .ari in our case), saving the project and quitting the app. This happens both when individually disabling the Conform Lock and switching to the camera original footage, or by right-clicking the timeline in the media pool and selecting the Reconform from Bins option. When we launch Resolve and open the project all clips have set speed at 100%.

I've tried everything from copy pasting the conformed clips to a different track, between timelines, exporting the project prior to closing it and then re-importing. In all cases the speed changes/re-time curves are lost.
