[Plugin: Jetpack] Gallery carousel

Hello everyone,

I use the theme Duena and therefore I’m not able to use the gallery carousel of the plugin “Jetpack“.
The theme uses custom gallery settings but I need the default ones for Jetpack to work.
(Thats what in my opinion is the reason for the problems)

Does anyone in which way I need to alter my *.php sites in order to be able to use the default gallery?
