Modern PnP - Search Results will exclude the document that have been copied

Question

I have a document library which contain around 7500 documents:-

and i defined the following PnP - Search Result web part >>

but the content search is only showing 9 documents >>

where those 9 documents were manually uploaded, while the remaining documents were copied using Power Automate workflow or manually from the 9 documents.. so is there a reason why those documents are been excluded ? and can i include them? as those documents are showing inside the SharePoint built in search box, which means those documents were indexed...
