Mod Help: Can't make portraits work properly.

I downloaded three mods (they're recommended together) for WOTR: NPC Portraits, NPCs Portrayed, and Everybody's Somebody, and followed all the install instructions, but it's just giving everyone hideous in-game model portraits instead of the nice ones in the folders.

I thought the issue might be that I have my Steam games on a dedicated drive separate from the C drive, so I tracked down the local files version on the C drive as well and replaced those too, but it still didn't take.

Any idea what I'm doing wrong or how to fix it? I'd rather have NPC portraits than these, but at this point I don't trust myself to try and revert it without making things worse.
