Unclick the "unsteady particle tracking" box in the DPM window then this start and stop time will not show up in your injection tab

In the DPM tab you should have your particle time step size and number of time steps. The product of these two is the total time the injection will be calculated if you want a continous injection you can set your start time at 0 and the end time at this number. I think that will work but I have no used this unsteady particle tracking with a steady state flow myself. Best of luck!
