PO Personalization to disable unit price for some Item Categories

Hi

We want to configure a Personalization in PO module

Form: POXRQERQ

What We want is that only  when the Item category be in the categories ('DOA NRP','DOA RP', 'DOA CL', 'DOA TP') the  price field remain enabled for some users

For this We got the Show Events

For the Item Category

LINES.ITEM_CATEGORY

WHEN NEW ITEM INSTANCE

Based on that the personalization was configured on this way:

However  it is not working, the unit price remains enable for all the item catagoeries, it is like the condition is being ignored

Could someone give us a hand  with this?
