Missions converted to projects - survey areas, flight routes and specifications lost

I planned and flew many missions in 2018 and 2019. Now when I log in on android, iOS or the web all of the parameters (flight area, settings, etc etc) for those missions are gone … most have been converted to projects and clicking on them just zooms me to the location of the pin.
We need to be able to repeat precisely the same missions year after year for ecological monitoring.
Can those pervious missions be recovered?
