I've been trying to fix this with AI before coming here, but not having much luck...

In DisplayFusion 12.1.1, switching wallpaper profiles with the slideshow running causes the next timer update to use the previous profile’s image source. Pressing the same profile hotkey again uses the correct source. Switching while the slideshow is paused works.

From some of the troubleshooting:
10:05:41: You select zSys-1920, but immediately afterward the slideshow chooses images from the previous Planets-Distance folder. [Log evidence (line 857)]

10:06:00: You press the same zSys-1920 shortcut again. DisplayFusion says that profile is already active, then selects images from the correct folder. [Second-press evidence (line 947)]
