Wallpaper resets every time I restart my OP3T

Hi, I just updated to the latest Open Beta and when I started my phone this was the wallpaper, https://imgur.com/gallery/wAFhO I can change the wallpaper but then whenever I restart my phone it resets back to the pink one.

Any help would be appreciated🙂

EDIT: I figured out how to fix it, You need to switch to the oneplus launcher, then set your wallpaper, and then switch back to your custom launcher.
