"Edit Page Size" drop down list; each entry duplicated
When using the "Edit Page Size" button/drop down on the Pages panel, the list of page sizes has begin showing duplicate entries, and I'm not sure why. It seems to have started out of nowhere.
To select an item in the list, you can see in the screenshot that each entry is doubled, and sometimes the "top" item is the correct one to click, other times it is the "bottom" item. In each pairing, one of them does nothing when selected.
I've attached an image to show what I mean.
