Actually we did. It is an endless loop. See, Barry stopped Savitar after Savitar gets out of the speed force and kills Iris. After the original Savitar dies, the time remnant of Barry goes back in time and becomes Savitar. Repeating the cycle again. It really isn't that confusing compared to other time travel plots.

Also it not being like the comics is common practice in an adaptation.
