IMAP Email Content - Can't work with 2 sensors?

Configuration
1

Hello,

Been tearing my hair out on this one, I’ve had a working IMAP sensor for my alarm working for a while, and wanted another one to work the same for my UPS (emails sent via Synology NAS). Spent ages getting the UPS one working - seemed to not work if my search criteria for the subject was too long, but got to the bottom of it. Now the alarm sensor has vanished, showing on lovelace as not found and doesn’t exist when looking for the entity. Can there only be one? Surely not.
Config pasted below.

Thanks in advance!
