there is no save button

Hello,
I'm faced with a situation where I am not able to save something in tab " Catalog ".
I only have a button " Close "
in the tab " System " everything works correctly.
Does anyone have any ideas what may be causing this? Thank you in advance for the assistance.

Hello Tomasz,

Please re-download latest version of EShop from our site and update it again to your site, then it will work normally.
