In this very specific type of circumstance you can 'usually' (but not always) make the seat assignments "stick" by following the links through all the way to print boarding pass screen. I don't recall the exact wording but follow through all the way to the end and click on the link that produces the page to print the result. Then log back in to make sure it stuck.
