Things seem to be working logically now. Arrows are pointing where they are expected.
At my latitude, the yellow line for alt adjustments is orientated at 10 o'clock to 4 o'clock. Green line for azimuth adjustments is orientated at 1o'clock to 7 o'clock.
I can now get a PA error of less than 10 arc seconds dialed in within 1-2 minutes.
