No pinit button on gallery images after update

Hello, since updating to the latest version of the plugin, the pinit button is no longer showing on the native WordPress gallery images.

Looking at the source code, the pibfi_pinterest wrapper and associated code is not even being implemented in the DOM.

Normal, non-gallery images are working fine though. Why is this?

Regards,

James
