Performance Notification - no ingredients

I’ve had a performance notification for 8 of my items stating that the ingredients aren’t listed.

I’m a fairly big seller and am well aware of the requirement to have ingredients listed. All of the listings already had them included so I can’t understand why they are being removed. I have gone back and forth with seller support who keep reverting to " add the ingredients and wait…". At one point, I was advised to do a partial update as their system wasn’t reading the ingredient field properly. I did this for one of the ASIN’s. It reappeared for around 2 hours at which point I received another notification saying that I needed to add the ingredients.

I’m at a complete loss with what to do. Anyone had any similar experiences and know how to resolve?

Thanks
