It's a problem with this page property:parent

String part is not recognized anymore in has fields::Page; String, I've tried changing it to text, using difference cases, no spaces etc. but no luck.

Has fields::Page; Page gives no red link but Has fields::Page; Text does even though both page and text exist.
