Pagination bullet not appear, next slide stuck on loading when view in box

Hi. The plugin works great and I like how it is simple to use.

But I have few issues as below.

1) Pagination bullet not appear. Screenshot here: https://paste.pics/CDLNIhttps://paste.pics/CDLNI
2) Next slide stuck on loading. When I press the fullscreen button here (https://paste.pics/CDLO7) it can view the slide. But when I click the next/previous button here (https://paste.pics/CDLOK) it won’t load the next slide, stuck in loading like here (https://paste.pics/CDLP6).

3) I also would like to inquire if there is an option to view the product title and description in full or longer because there is a scroll box, then it should be fine if we can view the title and description in full. Screenshot here: https://paste.pics/CDLR7

Your assistance is greatly appreciated.
Thank you.
