Hey @rubyt
This is very critical situation, it should not be happening.
Your first step is to head to Settings> Store Activity Log
Here you will get every store activity rectify that,
If you encounter some activities which were not performed by you then check the collaborator access to see if someone is messing with your store,
Lastly if none of that helps try contacting Shopify Support, since you are missing a lot on the side of visibility of your product due to being low stock and being in draft.
Hopefully, it will help you. If yes then Please don’t forget to hit Like and Mark it as the solution!
