Rotary Assignment Mostly Works

In MSFS 2020, I'm using the Maddog MD-82 and I've assigned rotary knobs such as Altitude using AAO.  Specifically, these are the scripts I'm using to increase and decrease altitude:

INCREASE:

(L:fgcp_alt_knob1,·enum)·0·==
if{8192·23·+·(>L:fgcp_event,number)·}
els{16384·23·+·(>L:fgcp_event,number)·}
 

DECREASE

(L:fgcp_alt_knob1,·enum)·0·==
if{16384·23·+·(>L:fgcp_event,number)·}
els{8192·23·+·(>L:fgcp_event,number)·}

However, sometimes when increasing altitude (turn right) or decreasing altitude (turn left) the altitude will turn in the opposite direction for a few clicks and then start moving in the proper direction again.  Any thoughts on problems with the scripts?  Thanks!
