Missing Thumbnails in Boot Splash Screen

Debated dropping this into the bug reporter, but I thought I would ask here first! Running KDE Manjaro on Wayland with Plasma 6.0.4, and I saw the new Boot Splash Screen menu. Went to edit it, and it seems all of the images are missing, so I can’t preview any of them! (See the photo below)

Anyone have an idea of how to fix this?
