Suddenly I can onlysave my iMovie projects to my files

What happened? Suddenly I can only save my iMovie projects to my files. It was OK a month ago. Is this a “me” issue; have I done something to my options (I can’t seem to find the choice to reverse it if so). If I hit export on iMovie there used to be a photos app sign to export to my camera roll; but now I can only find the option to save to my files. Why would I want that apple? I rarely use my files folder -as all of us- anyways…
