My epub file that was created in Sigil validated and I successfully uploaded it to Amazon for the Kindle.

However, after purchasing the Kindle book to view it, I noticed that there was some formatting problem:

On the page the eBook opens up to when you click on the book title, there's this code at the top:
justify">Part I: Overview

I have no idea what that -- justify>" is doing there. It shows up in 2 different Kindle readers I have and when I checked it on my iPad, the "justify>" isn't there, but the Part I: Overview is in normal
size font when it has a header tag. It also is in normal font in the Kindle, despite there being a header tag there.

The strange thing is when you click on "Part I: Overview" from the TOC, it shows up normally - normal header font size and no -- justify">

Also, if you go to the preceding page or the page after Part I: Overview, then go back to the Part I: Overview page, it appears normal. It only shows the bug when you open the book and when you click 'go to beginning'.

This bug didn't show up on the original upload to Kindle. It only did when I re-uploaded it after the changes were made.

Any idea what may be causing this and what I can do about? Unfortunately, the problem doesn't show up in the Kindle Previewer that you can download to your computer. And oddly, even though the book is supposed to open to the TOC page (as it does in the Kindle Previewer), in the actual Kindle book that has the bug, it opens to that Part I: Overview page.

Any help would greatly be appreciated. I have my header tags from
the stye.css file in the epub file below.

Thanks!

h1, h2 , h3, h4, h5 {
text-align:justify;
text-indent:0;
margin-top:0;
