Filter block not showing, Publish button doesnt work, activation doesnt work

Hello,
I tried your plugin in the free version but it was full of bugs so I decided to buy premium.

Problems still occur after purchasing premium.

– Auto update key cannot be added – cannot be saved
– blocks must be saved by clicking on the preview, otherwise the details will not be saved
– the only visible block is the price filter, all others are not displayed. (All blocks have been added in the menu which is enabled in modal)

Thank you for your help
