i bugged my layout [closed]

so, just for the fun of it, I decided to download the spacehey mobile. I had a previous themed before that was still in construction but still I decided to see the themes in the app and changed one to see how it looked like. Pretty cool and stuff but I'll change to the previous later.

That later being some days after that change and one uninstalled app.

and now I'm on pc trying to change the theme but it doesn't change. Only like the profile box or smth. I deleted everything from the about me section and still didn't removed the theme.

Can anyone help me out with that?
