Reply to Midi mapping bug.

I've started a mapping on a midi controller using traktor pro v1.xx and just ported it over to v2.5 to find that all the 'effect select' mappings are now bringing up the wrong effects in v2.5. The only one thats working as expected is 'delay', which I'm guessing is because its at the top of the list of effects in both versions.

Is this a known issue.. any info on how to resolve this, without remapping the effects again ?
