Can’t have 2 working page

Hello,

I tryed this plug and it’s axctely what i wanted.. I4m ready to take the pro version but I have one problem.

I build one page.. one gallery.. ok perfect
I build a second page, with another gallery.. ok perfect.. but then the first page doesn’t show the galery anymore.

I tryed to rebuild the first page but then, the second gallery doesn’t show anymore.

in fact it doesn’t show the galery 100%.. I’m not sure
I just know it’s working well only when I’m logged to WP
