Hello,

You’ve probably ordered the attributes by name or any other column. To turn this sorting off, please click the heading of the first column (see the attached screenshot). The arrows will activate then. (If you place your mouse cursor at the disabled arrows, the hint with instructions should appear.)

In case of any trouble, please write me back. Thanks.

Regards,

Vladka
