ES_OUT_SET_ES_LIST Will loop through all ES and deselect any currently
selected ES in the same category if it’s not in the list.

ES_OUT_SET_ES doesn’t do that. It only deselects one track and selects one.
(Maybe this is the real problem - ES_OUT_SET_ES might need to be updated to
use the same deselection as ES_OUT_SET_ES_LIST rather than using p_main_es)
