"Extract common metadata" not extracting Title from PDF when Import action is used

Try to import the zip into a space (which has extract metadata rule) title is not being extracted, Only author and description are extracted. But, if i directly add the pdf to the space, then title is also getting extracted.

Steps to reproduce

1. In Alfresco Explorer, create space “testfolder1”
2. Create a rule in space “testfolder1”, action "extract common metadata"
3. Using Import function to import zip file(please see attached) into space “testfolder1”.
4. Title will not be extracted, only author and description fields will get extracted.

Expected Behavior

Title, author and description should get extracted.

Observed Behavior

Title will not be extracted, only author and description fields will get extracted.

Note that if the PDF is uploaded directly rather than Imported from zip, Title is populated as expected.
