If you're looking at a product record and you see an "Unlike value" field in a given attribute that means that you have more than one store selected and the stores selected do not share the same value between them.  If you have 2 stores, as an example, and they have a different price for a specific product, say $1 and $2 respectively, if you check them both it will show "Unlike value" for the price.

  • If you select one of the stores you'll either see $1 or $2 depending on which store you chose.
  • If you have more than one store select and you change the value you will be updating the price value for all store locations.
