Mixdown problem with SB live 24 bit

Whenever i mixdown, thw wavw split into different channel say mixdown_ch1, mixdown_ch2. How do i mixdown into one wavw file.

it almost sounds to me like ya got two many audio devices selected,go to file,then prefrences,then settings,click on audio devices button,highlight one of the recording sources in each the playback side,and the recording side,this should help that,you probably gotta message before mixdown askin if you wanted to vmixdown all the different channels,i had this happen to me too,hope it helps ya

Isn’t an SBLive 16bit-48k ONLY???
