Dynamic / Pointer input changes units

[JDowls]

Looking for a little help with something that has been frustrating me over the last few months. Started a new job, AutoCAD already configured on the laptop. For the life of me, I cant figure out why the dynamic/pointer input switches between Architectural units and Scientific units while the mouse moves. For example drawing a line, sometimes it shows the arch units (8'-9 23/64") and sometimes it shows scientific (1.074880E+02). This is the same polyline command, just moving the mouse a bit further right. Does anyone know how to fix this?

It's actually acting correctly, according to Autodesk.

 

Move in a straighter line and/or adjust precision.
