No search box on loaders lists

I just noticed possibly in the recent updates of the last 24 hours that the search box that appears on top of the lists in model loader or lora loaders, etc, is missing.
This doesn't happen if I press clear to clear the workflow and start fresh. In this situation the search box is there.
If I load any other workflow the search box is missing and typing anything simply doesn't work.

I've separately erased the installed custom nodes and the problem continued to exist.

Anybody else having this problem?
