lightbox gallery no longer working after update?

I am using your Image Expansion Kit. Prior to applying the recent update to v 1.3 the lightbox gallery was working perfectly on single record images. Now since v1.3 it no longer does. Image will open in lightbox but the left/right nav arrows are gone, and clicking outside image does not dismiss lightbox. User has to use browser back button to return to single record. No errors in JS console.

When I delete v1.3 and reinstall v 1.2.3 lightbox gallery functionality returns to normal. Nav buttons are back and works as expected.

Cant link to page since it is password protected and contains private customer data.
