why did my mapping suddenly stop working

why did my mapping suddenly stop working

for months my custom mapping for the f1 has worked fine. now today suddenly one feature stopped working.
I have the encoder on the f1 mapped to move the cue/loop size around the waveform. encoder controls deck A and shift+encoder controls deck B. Like i said its worked perfect ever since i first made the mapping but now shift+encoder does not work for deck B. everything else works fine. ive reloaded the mapping and re-confimed the mapping everything looks fine to me. Could i be missing something? is this something that sometimes happens?

Try deleting the commands and re-adding them. I had it happen in one of my mappings before. Not sure why it happened though.

thanks vangogo for the reply.

i have found a solution and am good to go again.
