Panopress thumb disappear

Hi there,
I am using Panopress plugin for 360 interactive panoramas and I came across the problem which seems to be related to the theme so I wonder if you could help. Here is the example of the page – http://rapturousmedia.com/services/360-aerial-photography/
1. click any thumbnail to open pano in full screen
2. close pano
3. after clicking to another thumbnail the previous thumb disappear from the page

Another user of Panopress having the same problem described that after clicking second thum “the width and height style disappear … element exists but the width and height style is not on the PP_(X)”

It is not a general problem of the plugin. Here is the page where everything works ok and thumbnails don’t disappear.

It would be great if you could look into it and see if you find solution or could point me to the right direction.
Many thanks!
Ondrej
