Delete all translations

My Weglot dashboard shows that my current usage is 10,000 out of 10,000 words. Investigation showed my translations list includes pages from my staging website that were not deleted when I migrated the site to production. It also includes pages that have been deleted, numbers, file sizes, phrases where the translation is the same as the original phrase, etc. It looks like all of these translation count toward my quota. Is that true?

My immediate concern is getting my usage below 10,000. As such, how can I complete all translations and start over with my production website? Second, is the resolution of the above problems on the road map? If so, what is the estimated time of resolution?

Thank you for your assistance?
