Anilist auto sync issues

I used Anilist to import my list, after i exported it from that very popular anime site we cannot mention here, because there's no file import option. Today i noticed ALL of my list has been cleared, its still on Anilist but the auto sync bugs out and deletes your entries from here, it happened to me on "that very popular anime site that cannot be mentioned here"(even though its no longer) too until i disabled the auto-sync.
