Modern Communication Site - News WebPart - Page Property filtering

Hi All,

Have a strange issue when filtering based on page properties within News webpart in communication site. I created few managed metadata site columns (My Language, My Market, My News Type) in content type hub site & these site columns have been added in 2 different content type (News CT, People News CT). 

When I edit properties & try to define filtering based on page properties, the only options available is "My Language" & "My Market". "My News Type" column doesn't appear in Property Name while filtering based on page properties in News webpart.

Have ensured that pages has been created based on values for all these 3 columns & also have re-indexed site/page library, but no luck. Any guidance what is missing, please? Thanks.
