I understand the confusion as I was confused myself for the same reason. I also attributed that to my english language level.

But I think they just used title-case[1]

Short, minor words are usually not capitalized, as stated in the wiki article; esp. if they would cause confusion!

As far as I know, that rule doesn't apply to verbs. Do you have a style guide that indicates otherwise? I know it looks like I'm trying to correct someone's grammar online, but I'm legitimately trying to learn. Your comment made me curious so I searched for a bit but couldn't come up with anything.
