[Plugin: NextGEN Gallery] Loading issues

I have created a gallery and split it up into categories using tags. When you move between categories the image numbers from the previous page/category remain in the same position, and when you try to open the image in the new category, the old image opens.
It seems it is not refreshing correctly.

Also, when moving between categories the layout often goes out of whack with big spaces and has trouble displaying right.

Please help!!!
