It turns out that I needed to use the Options in LAYFRZ. LAYFRZ in Express tools needs the option "entity level nesting" selected to be able to individually freeze layers in an x-ref. If the options is set to none, it treats the x-ref like a whole entity.
I can't freeze layers on x-refs. When I click a layer to freeze the x-ref it freezes the entire x-ref and not the layer itself. I have other coleagues here that can freeze the layers of an x-ref. Which option/command do I need to use to remedy this?
