Value for 'color' attribute contains incorrect value in row..
When i want to import products and i perform the check before importing i get an error that my color attribute is not valid it says like: Value for 'color' attribute contains incorrect value in row 146,75 etc.
But i checked the data in this row and its fine because i checked it a few times and it's weird that in for example in row 75 i have the color 'Grey' and the same color in row 146,75 etc but it says then that this data is not valid.
Is this a known problem? or does someone know how to fix this.
