Sidebar Widget is showing wrong content

Hi, Im using you plugin to display a NextGen gallery with different content for each page, for example in the left sidebar, at bottom, here https://cu-2azk31h-nycwatershed.pantheonsite.io/forestry/education-training/urbanrural-school-based-education-initiative/

The problem is that the sidebar widget in that page is not showing the images contained in the gallery selected. At first I try to contact NextGen gallery support, they enter to my site to check and tells me that WordPress Page Widgets plugin doesn’t make use of all of NexGen Widget’s attributes and this is the problem, and suggest me to contact the WordPress Page Widgets plugin developers to report this issue. Could you help on this case? Regards, Pedro.
