NG Gallery on Custom Post type

Hi Alex / anyone who can contribute to solve this issue,

I am trying to load the gallerylist with pagination onto a custom post type and it fails.

i have just tested the normal pages and it works. here is a normal page.

check at the bottom of the page and it works well.

and here is a customer post type I have for resort islands.

this one goes to 404.

Galleries page created with Albums also look good.

is there are way to fix this as i have some galleries with over 200 pictures and disabling pagination will stretch the page too much.
