Assigned express pick tasks not coming up in Telnet

Task is assigned and when the user navigates to express pick in telnet the task does not come up and no message was received.

This began mid-afternoon after having no issues prior in the day.

After testing a few things we've determined that it is tied to the priority that the tasks are assigned.

Tasks that are assigned over 900,000 are working and lower priorities are not.

Does anyone know why the lower priorities would not come up?

We are on R12.  I recall having a similar issue a very long time ago on 11.10.2 but I don't recall the solution.

Thanks,
