Jetpack Tiled Galleries Conflict

Hi There

I am using the Expressions theme for our site designgel.org.nz, and have been enjoying it so far, with some customising on our end.

However, I have ran into a conflict with the Jetpack plugin, particularly the tiled gallery feature. The option to turn the tiled gallery feature is supposed to show up under Settings > Media, but it doesn’t.

I have tried deactivating all of the other plugins I am using one by one, with no change.
