Duplicated listings? eBay offcial please help?

[alittlepanda]

I got this notice earlier: 

It appears that you aren’t complying with eBay's Duplicate Listings policy. We understand that this may have been an oversight. Unfortunately, we had to take the following action:
- Duplicate listings have been removed.
- We have credited all associated fees except for the final value fee for your listing(s).

Ok eBay had removed 10-20 of my listings which they identified as "duplicated" that is not right, ok removed. However it gave me 7 days to organize my other listings or will be taken further actions. 

? I sell auto parts, some item fits a wide range of vehicles that I had to do multiple listings for different vehicles, used different pictures / prices for different vehicle, that considered duplicated?????

I do not have a standard of what eBay team consider duplicate listings and how am I going to start??? please help.
