Can't do negative azis Azimuth on "Bifacial system" Input

[Tokoyoshi]

I had the orientation at -9 degrees azimuth and going into the Bifacial system > Unlimited Tracker 2D model> Axis Azimuth can't go -9 degrees.

Before defining the Bi-facial tool, please make sure that your system is really compatible with a tracking array, horizontal axis orientated at -9°:

- In the orientation part "Horizontal axis, unlimited trackers",

or:

- In the orientation part "Tracking, tilted or horizontal axis",

- And in the 3D part you have to define an array with Azimuth = 0 in the tracking parameters, and rotate this whole "rectangular" object by -9° in the scene.
