Only changes first 10 products

I really like the idea behind your plugin and it seems to be working as described. But there seems to be a limitation that when I select a category to add an attribute to it only changes the first 10 products. I have over 200 in a particular category.

Is this a limitation of the plugin?

Thanks for your help in advance.
