pa_proj_elements - how is this table populated?

I'm curious about the table PA_PROJ_ELEMENTS, specifically how it derives its information in the field "NAME".

I am trying to enter a task_name "Contractor Contingency", but the column is only 20 characters wide, so the last two are cutoff.  We have a third party application that checks "PA_PROJ_ELEMENTS" column "NAME" for "Contractor Contingency".  That column is 240 bytes, so it is not restricted to the size that PA_TASKS' column TASK_NAME is limited to; however, it looks like "NAME" derives its value from "TASK_NAME", so it is the truncated version.  Surely these don't have to match exactly, because "NAME" is varchar2(240 byte) and "TASK_NAME" is varchar2(20 byte).
