Hello, would need some help mining Quarkchain QKC

PhoenixMiner working well for me for a long time and this is not my problem.

i took from binance a QKC address, write in miner, mining on qkc.ontopool.com. all was working without issues for hours.

So now the problem: qkc address from binance - and never had issues when i took for testing one address from them - looks like "xyz" 


BUT ontopool "makes" from it "xyz000000" - all other mining adresses there also look like this! - so i have coins on "xyz00000" but cannot take them, ok its maybe 2$, so not worth


but what i make wrong?
