Tumblr not saving changes to my theme?

[katlyn]

like i click save and it dose the little save animation thing but when i click exit is says ‘exit without saving?’ even though i saved. im just trying to change my title and change my cornerimage. the last time i changed anything on my theme was last week and i had no problems with it saving any of the changes i've made and with the theme im using i don't need to go into the html to add pictures to by theme or anything like that so im not having a problem with code editing

my customizer looks like this before i make any changes

notice the save button says 'saved'

and this is what is looks like i've made changes and saved

http://tinypic.com/usermedia.php?uo=a6BM...p-ojeKokz0

now the save button no longer says 'saved' even though i pressed 'save'

i've heard to try refreshing the page then saving and that didn't work
i've tried the /customize-classic thing too and that didn't work either

this is the same theme i've been using for months and i've changed my title and cornerimage multiple times so i don't know why it just started giving me problems all of a sudden
