Reminder Notifications from 2,373 Hours Ago!

As of yesterday I’ve started getting a SmarThings notification on my phone that reads “Reminder: water detected by the Furnace 2373 hours ago”. The current status of the moisture detector by my furnace is dry.

If I click on the notification on my phone SmartThings starts to load but I get a red message box that pops up and says “You appear to be having issues with your network. Please check your network connection and try again.” If tap the SmartThings app from my phone it loads just fine.

I have no idea why I just started getting this reminder. Does anyone know how to clear the history of a device or why this might have just started happening?

I’m running SmartThings v 1.7.5-0-21 on my Pixel 3XL.
