DJ Tech Dragon Two Mapping problems

[ZagaDj]

Hi.
I downloaded a MIDI mapping for my controller DJ Tech Dragon Two.
Here is the link from the forum:
viewtopic.php?f=401&t=35993#p206955

It works good but the only thing that I can't do is to activate the sound in the headphones: the Cues buttons lights of channels A and B are always with light on and when I push one of it to switch on the sound in headphones, the button lights intermittently and the sound does not come.
Can you help me please ?
Thanks a lot!

Does it work fine when you use the Cross interface?

Hi.
I use Cross DJ DVS and I loaded this mapping into the MIDI controller list menu of the software.
The controller generally works fine with this mapping but I just can't activate the CUE sound in headphones:
the Cues buttons lights of channels A and B are always with light on and when I push one of it to switch on the sound in headphones, the button lights intermittently and the sound does not come.

P.s.
sorry for my English...
