IM 153-6PN HF V 4.2 optional package is not installed

Dear sir,

While opening the hardware configuration the IM-156-6PN- HF V 4.2 i am getting this pop up and if I acknowledge it, my IM is showing as dummy object. I have updated the Gsd files. My hardware components with the same part number and firmware version  is present in the hardware catalogue. I have updated the hardware catalogue also, still the problem persists.

Part No:I6ES7 155-6AU00-0CN0 (fyi)

if I open the IM I get the following error message.

The "Dummy" tab provides information about the module type and its location. For modules with interfaces, it provides network information, such as the station address.

The current version of STEP 7 does not have the required "module knowledge" in order to represent the module and its properties. This module was either configured with a later version of STEP 7 or a necessary optional package is not installed
