Can someone help with intensity changes for ccminer

What I've tried: Go to Managed Software > CcMiner 2.2.4 found the line for the algo I wish to modify (Phi) entered --intensity=20 in the User defined Command Line argument I've also tried -i 20

Result, miner starts up, and within seconds the window disappears...

when looking at the logs, I can see that the default i 25 is in the command line argument, along with the values I input into the Managed Software section.


Help? please.
