Using AP Pagination changes existing article formatting

Hi, this looks to be a nice plugin, which I have been looking for, however I notice it's not respecting fonts in the space where you leave your content (denoted by please insert text here).  Is this meant to work, or not implemented?  If it weren't for this I would probably purchase as I don't think I've seen anything better.

I also note that your pagination tabs are only highlighting the current page (via shading) on the bottom tabs, not the top tabs.  Maybe just because it's the latest version of wordpress?

Looking at it a little more, this is my scenario, there are four named tabs.

The first tab, the font sizes are as I originally had them, that is to say there are H2 and H3 headings and general paragraph body text which all looks normal.

When I click the second tab, the content shows up as a mix of H2 and H3 content, which is not as it was originally.  If I disable your plugin, the fonts go back to normal, that is, H2 heads with normal body text etc.

The third and fourth tabs are the same problem as the second tab. And just for good measure, clicking back on the first tab, still shows normally formatted font sizes.

Seems like a bug, or perhaps there's something extra to the plugin I don't understand.  Can you help?  Looking around, you're actually the ONLY plugin that I like for pagination so far.

Thanks.
