Stocked product converting to nonstock product (Services)

Dear Members,

I'm in a process of converting stocked items to non stock service items but after recalculation and conversion those service items still showing on the inventory value report with zero value and zero quantity 

I want to make sure is is there any ways to remove it from the inventory value report or it's standard ?

Below is the process that I have done for conversion items  

01)  Make inventory on hand as zero by movement journal 

02) Recalculated the inventory 

03) Removed the BOM versions from the item

04) Created the new item module group as temporary 

05) Convert the items to service by JOB 

06) Product information management > Setup > Conversion > Convert to products not stocked 

but still showing converted items on inventory value report with Zero value 

Kindly advise is there anything I missed on this Process or as standard it will show in the value report 

Your responses highly appreciated

Thank you
