Jess, Try and update your distribution point. The version of the Package that you are distributing might be different from the version available in the Client assigned distribution point.
The dependency checking algorithms in the SCCM task sequence will identify and report the absence of a referenced package or application. Still, it will not identify version mismatches before the task sequence begins.
So, try updating content on the distribution point. If it is an SCCM application, delete historical revisions too.
