community theme

[alibraryofunreadbooks]

 hello, I'm having some trouble with my community theme and I'm trying to figure out if its a troubleshooting problem or something else.

ive started a community called mapmakerstrilogy for a book trilogy and I'm in the process of editing the  theme and adding background images. I was trying to change the theme to sand dunes by flatlanders but everytime i do it automatically applies it to my blog instead of the community. by all accounts my settings are correct and I'm working in the right community so I don't know why its doing this.

are there certain themes that are only allowed to be used for blogs and not communities or is this a troubleshooting issue? I've cleared my browser cache as far as the begining of the month and restarted and updated my computer. I don't know what else to do.

any advice is appreciated. thank you!

edit: here are some screenshots of what is happening. sorry for how large the images are
