For some reason recently my designer files will no longer open with designer when I select them. They default to opening with Photo. I can right click and then choose to open with Designer. The extra click is slightly annoying but I can still work with my files. Weirdly but I can't fix it permanently. First, I chose get info; but  I couldn't change the file options there either as the movie below demonstrates. Then I tried uninstalling & reinstalling both photo and designer. This might have all begun when I installed the Publisher beta. I'm not sure.   I'm on a MacBook Pro. Details pictured below
