Cannot see steps in MT5

For some reason I cannot tick to test the steps in MT5 input paramters. Is there a setting that I need to activate in another screen to make this work?

I guess you have changed the Optimization setting in the Settings tab of your Strategy Tester to anything other than Disabled, right?

I had it as all symbols selected in market watch. Thanks for you help. Looks like it's ok now.
