Fix stranded inventory issue

I sell most of my product in the UK via FBA. I also have the product listed in the French Amazon site, but it is not stored there, just shipped from the UK.

What concerns me is that I get a message saying that I have a stranded SKU scheduled for automatic removal. They will destroy the product if i don’t get it fixed. But my product is stored in the UK selling to UK customers.

Why are they saying my stock will be destroyed? I am very concerned about this.
