"Share above target" is probably something with the pool expecting a faster miner (more shares coming in) and it could take a few minutes to retarget.
NiceHash and proper cgminer don't work well together, because NiceHash requires some added protocol stuff that's demonstrably insecure and kano refuses to support it.
I'm still getting the Share above target on Kano where I have been running all morning.
Does this help?

Looks like you have the "--verbose" command in your config/bat file. Take that out and see what you get listed on the cgminer screen.
