azurewave 7022 dvbs box diseqc

I like this program but i have aproblem with diseqc
i have 2 satalite(nilesat and hotbird) in a 4 ports diseqc
the problem is that there is many frequancies in both satalites like(11296 in hotbird and 11938 in nilesat) can not working when i use the diseqc
if i remove diseqc and make it direct to lnb nilesat or hotbird and put one satlite the all frequancies of sat work correctly

so i think there is problem with azurewave bda device
help me
