Bugs in content types

With the iframe embedder, I am having mixed results.  Some of the URL address that I am using are working and others do not.  Can anyone shed some light on this issue?

We've discovered that when using the export text option in Documeation tool the docx generated only properly format down to h2 level headings.

We used a few <h3> text in our exmaple and they came out with the <h3> tags and all the other formatting tags applied to it as it is. That is they looked something like "<h3><strong>some sample text</strong></h3>" in the Word document generated.

Using the 'select text' option then paste into a blank Word document had no problem.

We are using the WordPress plug in.
