[Plugin: NextGEN Gallery] Navigation problem

Hi,

I have 2 problems with the plugins in my page

I use different gallery in one page with
[nggallery id=2 template=caption]
xyz
[nggallery id=3 template=caption]
zae
[nggallery id=4 template=caption]

1°) when i navigate in one gallery with next page button, all gallery go to the next gallery page on the page

2°) when ajax is on, when i navigate i lose the caption dispay

Is there a way to solve this or is it a bug ?
Thanks for answer
