Xbox replay editor cuts first second of exported video

This is something that started happening I believe at 0.29.1 and is different, but still persistent in 0.30.1

Whenever I export a replay from the editor, it cuts the first 0.5 to 1 second (I think depending of replay speed?) from the start of the video. It is really annoying to work around. 

It's a simple bug. 

How to replicate:
Go to replay editor
trim the replay to a certain size. 
Export the video
Open the video in the xbox recordings app, and see the exported version is missing half a second to a second is missing from the start when you compare it to the placed trim marker. 

expected behaviour: 
The part of the replay that I trimmed, should be the part that is exported. 



Thanks.
