Alert Bubble alerts ignores temperature type setting
Update 1: the email alerts also were using the incorrect temp type.
Update 2: after a reboot of the system, the alerts and emails now show the correct temp type.
So, it appears that CDI will not pick up those changes until it is restarted perhaps?

I have selected Fahrenheit for the temperature type, but the alert bubble that pops up with temperature warnings display the temp in Celsius.
