Reply to Issue with MF3D "jam on it" mapping and v2.5

I have an issue where the beat masher combo/transpose effect comes through on Deck A, regardless of whether the Deck A bank/(FX ON A) button is engaged. The beat masher itself (using FX unit 3) doesn't come through, but once the transpose effect comes in (on FX unit 2), it comes through on Deck A. This doesn't happen on decks B through D. Where should I be looking in the mapping to fix this?
