Strange persistent notification bug since update, any ideas on what's causing it?

Hi all, I switched to CachyOS with KDE Plasma from Windows a few weeks ago on my desktop PC and it's been a mostly great experience. Only have had minor issues pretty specific to me with niche streaming/gaming software, but today I've gotten a weird issue after updating with Cachy-Update where popup notifications (like when extracting a zip) won't go away even though they should after 5 seconds like they did before. They also say "undefined" next to the application name, example here.

And yes, I've checked settings to see if popups are set to hide after a few seconds and they are. Also trying configuring for specific applications but neither Dolphin or Ark show up when searching even though they're clearly installed.

At the very least, could somebody tell me if this is more a KDE or Cachy bug? Any thoughts on how to fix it besides rolling back snapshots?
