Add component dialog box not functioning


I just switch to Mojave and the Add component dialog box seems to be broken. I can’t have any suggestion or can’t select a glyph to make a component. See the screen capture. That’s kind of weird and frustrating. Any ideas? Did I missed something? Can I get it back any way?
Thanks for the help
