I am getting a ton of rejected shares when mining Keccak?
The error is

"reject reason: Low Difficulty Share"

This is happening on my 2 rigs (1 with 1060's, the other w/ 1070's)

Here is my stats page;
http://www.zpool.ca/?address=3C4DZ5aGsvtgsdGs7XpMbbV3KGus1A84LA

This is my .bat file;

powershell -version 5.0 -noexit -executionpolicy bypass -windowstyle maximized -command "&.\multipoolminer.ps1 -wallet 3C4DZ5aGsvtgsdGs7XpMbbV3KGus1A84LA -username garandhero -workername rig1060 -region usa -currency btc,usd -type nvidia -poolname zpool -algorithm neoscrypt,decred,equihash,groestl,lbry,neoscrypt,sib,lyra2re2,lyra2z,blake2s,nist5,skunk,skein,mygr,keccak -interval 300 -donate 24 -watchdog"

Am I doing something wrong? Why so many rejects (literally 50%)
