It's a huge pain that locally applied styles seem to take precedence over general styles, especially when you're copying over material from another program.
Why did OO implement such a counter-intuitive and counter-productive logic?

MS Word makes a lot more sense on this point, I must say.

In my case, I simply want all the Level 3 rows to have the same Font. Why should that be so hard? Since I've copied in the content from different programs, there's a mix of fonts. So, how do I quickly correct all the wrong styles in my document?

Here's OO's note on their backwards hierarchy:

In general, more locally-defined styles take precedence over more generally-defined styles. If you have a whole-document style that sets the font size to 16 points, and a row style that sets the font size to 12 points, the row's text will honor the 12-point style. You can check the Style Attributes inspector to find out the priority of styles being applied to the current selection.
