Basecamp tweaking aircraft GPS tracks to follow roads. How to disable?

I'm using my Vista cX with Garmin Basecamp 4.2 to track my progress flying ground reference maneuvers (flying specific patterns relative to ground landmarks).

When I download GPS tracks, Basecamp is 'tweaking' the tracks to follow roads on the ground.

Anyway to disable this feature? Thanks.

See attached screen shot showing a straight flyover tweaked incorrectly to follow roads. Will be trying 4.4.7 with a new air track later today, but didn't see anything relevant in the release notes.

Thanks!
