Inconsistency of the multi-variation can cause this error notification.
Example:
Color: Red Size:M
Color: red Size:L
eBay won't recognize Red and red as the same variation name, but won't recognize them as different either.
Solution:
Download Excel from attachment.
Copy all variations to this downloaded Excel. The yellow part will transform your variations with inconsistent upper and lower-case issue into the same format. The column on the right hand-side will show you which one has this typo error.
The Excel for multi-variation will revise the first letter to be upper case and leave the others in lower case. It may cause a different outcome than your initial upper and lower cases. If you saw many “Inconsistent” appear in this Excel. That means the real inconsistency is part of the multi-variation table.
You may copy the yellow part and paste onto your original datasheet to replace the multi-variation. Then save this Excel file and upload onto SoldEazy, verify and list.
