Can’t get it to work

This plugin looks good out of the box. However, most of the options in ‘settings’ don’t work.
Example: can’t turn off the dots. Autoplay not working. Ordering options have no effect. Responsivity is wonky (no extra dots and just displaying two logos per dots, so more that half the logos are invisible).
The only thing in settings that had any effect was the image size.

It’s a real pity because it looks good at the start. I guess all the good reviews are from people who just use it as is out of the box and never even touched the options.
