DT Lite mounts .cue audio tracks without .bin data track?

Hi,

I'm having some iffy behavior with DT and bin/cue mounting - mounting .cue mounts only
the audio tracks while .bin opens only data files.

This way, either my game doesn't work, an old game that requires a CD present,
or there is no music in-game.

Some screenshots to explain it better:

.cue file opened directly with IsoBuster:

.cue file mounted with DT:

.bin file mounted with DT:

Why can't DT read .cue and it's appropriate .bin file "simultaneously"?
