OrderCheck() failed: Unsupported filling mode (10030). MT5

[Jnmr1]

I built an expert that uses BUY NOW, SELL NOW blocks. So far the expert appears to work fine on common pairs such as, EURUSD, USDJPY etc. But on CFD's and as of right now one exotic EURZAR I get the error "OrderCheck() failed: Unsupported filling mode (10030)"
I am running the expert on an MT5 hedged account. Any help would be appreciated.

Broker name? Problems like this are reported over and over again and I fix them over and over again, but MQL5 works in unexpected ways for me and to fix some problem I need to be able to see it
