To reproduce, create a document (say Space.Page) with 2 jsx objects in it, both with "parse content" set to "No".
Navigate the browser to
Change the value of "parse content" to "Yes" for any of them and, when going to the same URL, only that one will be returned.
If both are set to have parsed content, then the first one will be returned.
General rule is that the first one with "parse content" set to "Yes" will be returned alone.
