The Output 1 Mode setting (stereo, etc.) is found in the I/O: Audio menu on the AX8, not in AX8-Edit.
The delay settings you posted won't create a stereo delay from a mono input (unless different modulation was applied to L/R delays). Try lowering the "ratio" parameter a bit to reduce the right delay time.
