Ethosdistro 1.3.3 Eth+Zec dualmining

Hy, I use my rig since a while in ethos now; mining only on claymore and ethereum with ethermine.org and I tried to change for dualmining recently. Still using claymore and adding Zcash. I've tried to find a solution and hints for a moment but no real details found. I've used my local.conf and claymore.stub.conf for the adjustments, but still no dualmining results. Only hashing ethereum and nothing on zcash. My config files contain following lines. Please have a look and tell me what I do wrong or what I didn't consider correctly.

Would although be great to have a fixed hashrate for each of the coins, maybe fixed association of gpu (9/4), or percentage (70/30) of overalls hash, if possible.

System:
Ethosdistro 1.3.3 on USB3.0, 13 gpu RX480/580, H110+, 8GB and Intel G4400 3.3Ghz.

I do not have trouble with mining, or ethos in general, all is working fine and stable, low energy consuming and heating the garage to 25 degrees Celsius ... but dualmining seems being different.

Thanks a lot in advance for your help and all of your suggestions!
