So it appears if you include decred in your multialgo it doesn't pick up the difficulty.
Tried this (decred at the end):
ccminerAlexis78.exe -r 0 -a blake2s -o stratum+tcp://blake2s.mine.zpool.ca:5766 -u 1B5NVnLrXRjzEsmBkSZiXpLbdmVn6qC5q -p d=32,myr-gr=95,lyra2v2=50,blakecoin=6.75,c11=22.5,groestl=50,blake2s=5.45,x17=12,nist5=60,skein=720,sib=16.5,lbry=380,timetravel=36,veltor=29,bitcore=18.9,hmq1725=5.6,decred=3.55,stats
or this (decred at the beginning):
ccminerAlexis78.exe -r 0 -a blake2s -o stratum+tcp://blake2s.mine.zpool.ca:5766 -u 1B5NVnLrXRjzEsmBkSZiXpLbdmVn6qC5q -p d=32,decred=3.55,myr-gr=95,lyra2v2=50,blakecoin=6.75,c11=22.5,groestl=50,blake2s=5.45,x17=12,nist5=60,skein=720,sib=16.5,lbry=380,timetravel=36,veltor=29,bitcore=18.9,hmq1725=5.6,stats
And it didn't pick up the difficulty from the d=32

And it does pick up the 32 difficulty.
