Missing submissions from multiple project forms

We are missing numerous submissions that were entered into multiple projects on the Kobo application running at https://eu.kobotoolbox.org. The forms themselves are intact and show no signs of modification but the submissions appear to have been somehow removed. Any guidance on determining what may have gone wrong?

Welcome back to the community, @markjadek! Are you the admin of the project or is it a project owned by someone else and shared with you?

Thanks @kal_Lam, yes i am the admin of the projects. (We have 6 deployed projects and the data is missing from 3 of these).
