Folder not seen by web server

I'm running Apache2 on Ubuntu 16.04. For some reason, there's a single folder that is not being seen by Apache (if it's even an Apache problem). Sceenshot

On the left is the directory and on the right is what's being seen. Everything except the folder "7.10.1" is seen. I've tried renaming and restarting the apache server with no luck. I'm not sure what's going on here. Any help is appreciated!
