If you got this type of error when listing a multi-variation item from AliExpress to eBay:

Please check out the names of the changing categories in your item - for example it could be "Color" or "Size". 

In case those are the names of the changing categories, you must make sure you don't have item specifics with the same title. In our example - do not fill or simply uncheck the "Color"/"Size" item specifics. :-)
