Color Change On Power Up

I purchased some Athom WLED Bulbs and have set them up in the WLED app and Home Assistant. There’s a setting in the WLED app for “LED & Hardware setup → Apply preset X at boot (0 uses values from above)”. I’ve saved the preset that I wanted (a bright white). When I turn on the switch, the light starts out at my saved preset but then a couple seconds later, it goes to the standard WLED power on setting.

Is there a setting I have wrong?

Possibly. Post your configuration and presets.
