Problem cached admin pages with persistent cache

Hi, i have problem on this page

/wp-admin/admin.php?page=anspress_options&option_page=addons

when i change any value, after refresh i will receive previous version of this page, that is cached

i have redis installed as my persistent cache storage, i dont have this problem on localhost, where is without redist, so there is somewhere a cache mechanism for this admin page, please check it, thank you
