Hello Pradeep,
In this case forget about Catalog Profile assigned to Notification Type. Catalog Profile assigned to Equipment will override that.
To me it seems you haven't created Codes and Code Groups for Catalogs B (Object part) and C (Damage) through QS41, one of which (B or C) is compulsory for you to use Catalog Codes information in Notification Catalogs & Codes Tab.
OR
You haven't assigned in the Catalog Profile the Code Groups for B and C in OQN6.
In this case what happens, when you click on the F4 help of Object part ( or Damage ) in the Notification Catalogs tab, you will not be able to get the list from your profile. It will display all other available.
If you feel this is not the case then you need to give screen shots of all for the answering persons to be able to detect the cause.
Best of luck
