Banners Missing

Hi - I just updated CS-Cart from version 4.11.2 to 4.11.5 and I also updated my theme to it's latest version. After the update all of my banners are gone (Marketing>Banners is empty). Anyone know what could cause this? Unfortunately I didn't check on the banners before I updated the theme so I don't know which one caused the problem.
Thanks!

At first try to login the phpmyadmin and check if the following tables contain records

- cscart_banners

- cscart_banner_descriptions

The cscart_banners is empty but the cscart_banner_descriptions has content.

The cscart_banners is empty but the cscart_banner_descriptions has content.

Something went wrong and information is lost now. If you have backup, restore it on local host and transfer banners data manually.

Ok, thanks for your help.
