Answer 1

I have master and develop branch. develop branch shows it's 20 commits ahead and 1429 commits behind master (ref Image 1) However if I compare the develop with master branch I see 8 files has changed (Ref Image 2).

The develop branch started from master some time ago. During this time, 1429 commits have been added in master , and 20 commits have been added to develop . In these 20 commits, a total of 8 files were modified.
