Components not getting displayed in the task list when a BOM is assigned to it

Hello,

There is a tasklist group '335'

Transaction - IA06

It has one operation , and it has been assigned the assembly 'LF-335' (BOM). But when i click on 'component' tab at the bottom , no components are displayed of that assembly

No components are displayed

And its not like that i haven't assigned any components to that assembly or BOM. I have assigned few components (materials) to it . Please see below.

Transaction - CS02

But why are these items not getting displayed in the task list?

Thank you
