Mobile Line Bug

Hi guys,
I’m using your great theme: Parabola.
Me and my programmer bumped into a bug:
On mobile strip, there is a consistent orange line that we can’t rid of. We have tried looking for it in the code to delete it, but we just can’t find it.
i would really appreciate if someone can assist me with locating it and removing it from the mobile strip (print screen attached).
Thanks a lot!
Moria.
