MP4 from Storyline imported to Replay - Video rewinds automatically

Hello,

I am currently working on a highlight video (using both Storyline 360 and Replay) 

It's a simple video, with a shape to highlight an area and pause/play at the same cue points.

The preview in SL works fine, there is no sign of irregularities.  I publish to an MP4 so I can import to Replay.  (There will be several videos compiled into one large video with audio throughout)

Once I import the video into Replay and hit play, the video starts, shows the correct triggers etc. and then, rewinds the video to the beginning plays like normal, with no sign of the triggers.

I've added both the SL and the Replay (single video only) as my example.
