Strange Issue

I had this wallpaper plugin working perfectly on a self hosted server, with the allowing wallpaper on outside walls turned on. I migrated the server to a new host a few days ago. Now, every time the server restarts blank wallpaper is added on the outside wall wherever wallpaper was used inside.

I remove the outside wallpaper, restart the server, and it comes right back again.

I remove the inside wallpaper, restart the server, and the outside wallpaper is NOT added.

As soon as I put the wallpaper back up inside and restart, the outside wallpaper is back.

I've tried wiping the config folder, booting the server without the wallpaper planner, redownloaded the plugin, and put it back in, letting it start fresh. The same thing happens. Any idea of what might be causing this or how to fix it? I dont want to have to turn off the option to place outside wallpaper...
