If you toggle in-place mode off and back on again, it should redownload icons from the set and display them.
I had that happen. Maybe this could be resolved 🤔

There's also a command you can run from the command palette called Iconify: Clear icon cache which fixed this issue for me.

There seems to be some named icons under the plug-in that does not support previewing

Another problem is that the previews seem to have problems with regular matching
