That is an example of the difference between Jewish and Christian versification. The chapter break differs by one verse. This is a relatively rare problem outside of the Psalms, but it is very frequent in the Psalms because the Jewish number system includes the titles of the Psalms which are left unnumbered in the Christian Bibles.
I have not analyzed the differences to see if there is any structural confirmation of who is right and wrong. I don't have any examples off the top of my head where it makes a difference, but if I think of one I'll post it.
