non active pagers

hi, trying the non pro version and it works great and as described, except for one issue.
The thumbnail pagers will only show the first image as ‘active’. Clicking the next thumbnail will advance the slide but the thumb for that slide doesn’t show as ‘active’ and the opacity does not change.
In other words, aside from the first image, the pager will not show any of the other chosen images as ‘active’.
