As I don't know your firmware / Megatune package version, here is a change that should fix this:
there is a row in MegaTune2.25\mtCfg\vemsv3.ini
als_launch_input= scalar, U08, 40, "", 0.0, 0.0, 0.0, 0
just change it to
;als_launch_input= scalar, U08, 40, "", 0.0, 0.0, 0.0, 0
or remove that line
the number "40" might be changed from 1.0.73 version, that this row is taken from
leave these without touching:
als_input = bits , U08, 40,
launch_input = bits , U08, 40,
