Not giving choice of "Just Once" and "Always"

As the title said, the phone doesn't give me the choice of always or just once, there's only a menu and I can click the app that automatically becomes the "default" app... It sucks as I need to save a pdf from Outlook to One Drive to then open it in write pdf but it won't since one drive is the default app and I don't get the choice...

How do I fix that??
