Priority list shows A-Z on task creation, but only A-E when re-prioritizing existing tasks.

[Confusedious]

The list to assign priority to a task on creation shows all A-Z choices if priority is assigned before the task is saved. After a task is created and you try to re-prioritize, only choices A-E are showing in the dropdown.

This behavior shows up on Samsung Galaxy S2 phone running Android 2.3.6 and Galaxy 7.0+ and 7.7 tablets, both running Android 4.04. All are running Todo version 2.1.

Temporarily, I re-prioritize tasks by editing the text file on my computer.
