Weather showing up as Fahrenheit when I want it to be Celsius

So I want my weather to show up in Celsius and I went into Open QuickControls > QuickSchedules > Weather Widget > and set the Unit to Celsius, so the weather that shows up in the QuickControls section next to the date shows up correctly as Celsius however when I expand it to show the 7 day period it still shows up as Fahrenheit. I'm running the latest version of AquaTouch v3.6.6 on macOS Big Sur 11.4. And under System Preferences > Language & Region > General > the temperature is already set as Celsius.
