Sounds to me like you may have hit the bug I reported in the 2.00 Firmware, in which moving a block onto itself (which should be a no-op) actually perma-horks (that's a technical term) the effect from that point forward. The only workaround I've found is to change that block to be empty, store your preset, turn the unit off entirely, then power it back up and go re-configure that block from scratch. And to avoid hitting this issue again, be sure to hit the EXIT button if you decide NOT to move a block, rather than hitting the ENTER button to just drop it into its same slot. Hopefully they'll fix this in the next firmware update so that any attempt to move a block onto itself effectively just cancels (same as pushing the EXIT button).
