AMP page is cutting letters from url

When going into the index page some post are giving 404 error because the plugin is cutting short some of the URLs. For example, posts that contain “/whatever-review/” on the slug, it gets changed into “/whatever-rvw/” and therefore the page won’t load.

From what I have checked, it’s only happening with “review” getting changed into “rvw”, but nowhere else.

Why is this happening?
