Backdrop Screensaver Question

[Dirty504]

I've recently noticed that the majority of my backdrops that display on my sceensaver are almost exclusively from my "kids movie" folder and that the same ones 20 or so will repeat several times, very rarely showing backdrops from other folders. 

I was wondering if there is some cache or something to clear/update so that all of my wallpapers are included in my screensaver queue.  I've tried searching and the only thing i've found is potential NSFW tags blocking backdrops, but I don't have any parental control restrictions or anything like that set...

Thanks in advance.

Which client? IIRC, the Android TV client has a setting for limiting backdrops in screensaver mode to more family friendly items.
