The anchor pull down under Format no longer has the option to anchor to page
It was removed from menu in tdf#135836 (but is available in properties dialog). Are you sure you actually need that anchoring mode? See also FAQ.
Don’t use Anchor to Page unless you really know what you’re doing. What users in fact need is to position the frame in the page but the frame should be kept anchored to a paragraph so that it moves with the paragraph.
