Just a thought...maybe others can tune in.
Item saids country of origin : Sri Lanka
Country/ Region of Manufacture : USA
And description has 'Ceylon' as a country in it.
We know Ceylon became Sri Lanka but eBay artificial Intelligence might not yet.
Maybe use the country USA for all three areas instead of 3.
You had 5 listings removed...it doesn't mean more will not be removed in the future...as maybe only 5 got identified by a person or company or eBay itself reported and de-listed.
I had the same problem where 5 got removed but had 55+ still with policy violation.
Anyway, I too love a mystery.
eBay does eventually will come back and let you appeal them...under not sold category...but I don't remember the time frame.
