Same ID but different books
I have been running the Duplicate book app in each of its options. Just when I thought that I had deleted all unwanted duplicate I ran the option comparing isbn id. That produced many books that had the same isbn number but had different titles.

Can someone explain how that could occur?

GIGO

When you 'download Metadata", those TRY to match if there is not already an ISBN. ISBN code really refers to an edition, not a title. My 1970 edition will have a different ISBN than the 2010 edition (no just another printing run).

Blindly accepting the results, can grab the 'best guess', with that guess being wrong. I use the ctrl-D metadata download and REVIEW the results and cherry pick each line.
