Styles showing category number, but not name

[BryanSparrow]

Good morning All,

I am trying to use some styles for symbolization that I imported, but the category number shows in the 'Symbol Selector' dialogue. If I hover over the symbol with the mouse cursor the name of the symbol shows in the info box. How can I get the name to show instead of the category number?

I'm using ArcMap 10.6.1.

Thanks,

Bryan
