Page Size stuck on A4 in 1.2.1

 When I create PDFs in 1.2.1, the paper size is fixed as A4.  I have tried resetting to letter in the Document properties, but it doesn't stick.  This means when printing docs, content gets shrunk a bit.  

When creating a doc, in the Advanced properties dialog area, it is set to "letter" but I still get A4 output.

Oddly, if I use a Custom size (set to 8.5" x 11"), I then get the correct size.  So, there is a workaround.
