Hi @john john Pter ,
Thank you for posting in this community.
If you use another "Source"filter to filter these files, can it work fine? You may can try to replace "All Sites in the hub" with "This site". Check if the new Highlight Content web part can display the correct content?
If everything is fine with a different filter, it means it's a timing issue, please be patient and feel free to contact me if you have any other questions.
