Re: setting defaults in wp-juicebox

We have just uploaded a hotfix version of the plugin which fixes the default settings problem.
Please download the plugin from the WP-Juicebox support page and reinstall it.
This should solve the first problem you reported.

I have just checked the functionality of the second problem you reported and it seems to be working OK for myself in WordPress 4.5.3 on my own server.
Once you have reinstalled the pluign, try completely clearing your browser's cache. A mixture of older cached files and new ones might be causing the problem.
