Hey Nastika,
Maybe this will help as your issue seems similar to mine. You have to sync/store to one of the discrete memory slots. Sending your configuration info to the Working Memory slot only persists your configuration to that volatile slot. In that situation, powering off the unit (i.e. disconnecting the USB cable) results in the Working Memory slot being reset to whichever memory slot is recalled via "recall" and one of the pads.
Good luck,
Spenser
