SharePoint PnP Search Result setting

Morning!!

I am working on a Knowledge base and using the PNP parts to make a good search page.

I added a vertical search and it all works OK provided i do not select Documents under "Result source ID"

If i select anything else, i can type something on the Search Box and the search goes across all my vertical tabs. If i select Documents: it will work on the main tab, but not on the others. 

When i select "LocalSharePointResults"

When i select Documents:

you can see not it brings all the documents on the site not only those with TEST 

Is that OK, or is my webpart playing up?

thanks
