Sharepoint 2013 Wiki history page always shows the first word as added

Question

When I change a word from wiki page, wiki history page shows first word as added. Although I not change the first word

this error always occurs on the first word of the page.

Answer 1

My test result is the same as yours, and the same behaviour in SharePoint Online.

So this should be by design. It is indeed a very strange behaviour but basically does not affect the use.
