Can't benchmark any dual algorithms. I'm getting "No pools specified" every time. Benchmarking single Ethereum works.
Found out why this happens - when you disable Ethereum for Claymore Dual. It still shows up in the benchmarking window, but benchmarking any dual algorithms then fails because it disables the Etherum main pool. Strangely benchmarking single Etherum still works though (even though it shouldn't even display the miner when its disabled).
For me it does not save any hashrate from the 2nd ALGO. So if I want to mine with "Claymore Dual 11" the best combination like Etherium+Blake2s it is not possible because on benchmark this combination is saved with $0.00 additional for blake2s.
