Imagine if you had 2 viewports in paper space, different rotations. You're showing the same spot elevation in both and they're rotated to match the view, great. Then you export to acad (same as what etransmit is doing). Only one of those rotations can be kept right? This is what's happening to your labels. Even if you have only one viewport, I believe the export to acad withing etransmit is doing its explodoing from model space where is has no idea about any viewport in paper space.
This is just the nature of exporting to acad, it's imperfect.
