My theme keeps switching

My theme is supposed to be set with a light blue colour to match my wallpaper and asthetic of my phone. But the launcher keeps changing it to the auto picker theme which makes it and orange/red which is quite annoying. This bug only happens when I switch my phone from light mode to dark mode and back to light mode again. I would normally just keep my phone on one theme but because I a mode/routine on my phone which sets it to dark mode when its night time and back to light mode when its day time this can be quite frustrating as I do not want to keep switching my theme back and forth :(

Thanks,

(Love the launcher btw this is the only bug I'veseen so far)
