Unable to change CFL in Fluent?

Hi,

I'm running a simulation on a cone in supersonic flow. My residuals decrease pretty well, but after 1000 iterations they flatline. I want to increase the Courant number to help the simulation converge, but despite changing the settings, it is stuck at 44.9.

Any help would be greatly appreciated. Thanks!
