Issue: sticky items remain on mobile

Issue:
Lightbox works great on mobile – except that the sticky item (caption and buttons) are always visible, even when those 2 checkboxes are NOT check in the settings.

Expected:
Tapping an image on a mobile browser should display the image with no overlays (sticky items)

Actual:
The ‘full screen’, ‘close’, and social buttons stay on screen and never disappear (portrait and landscape).

Device:
Android / Chrome (latest)

Notes:
I’ve cleared the browser cache, and the WordPress cache several times. I’ve even enable, reloaded, then disabled the sticky options (clearing cache between each).
