Map track error (straight lines in track file) but distance normal.

Hi All, 

Just curious if anyone else has had any activities where the resulting track on the map exhibits a section that is straight. Like as if the activity was paused, kept running for some distance and then un-paused? The distance for the activity is correct but the track file is not true to the actual path I've taken. I've attached a screenshot as an example. 

I've submitted a support case with Garmin and have sent them links to the activities (there has been a few this year) and it seems completely random. It's clearly a tricky one as it has been many weeks and I have not gotten a response yet. 

Not complaining by any means just curious if anyone else is seeing this?

 

Craig.
