Issue: One or more columns fail to display in either the products or combinations table even though they have been selected in the columns pop-up menu.
Explanation: The tables have dynamic columns to make working easier and quicker. Certain data is stored in cookies and in some cases these can get out of sync with the table.
We could fix this issue but at the expense of user comfort. Therefore, we have taken the decision to leave things as they are (the glitch is easily fixed with a couple of clicks) in order to preserve the application’s user-friendliness.
Solution: Fix the issue via the Catalog > Tools > Clear cookie data: product table preferences menu item.
