I've been having an odd thing pop up occasionally.
I use a Word template to edit my lit, pdf, etc files, then save as a docx file. I then import the docx and have Calibre convert to epub.
The strange thing is, only twice now in 16 books, I've had my <i class="calibre2"> (meaning italic) not show up, and get <span class="text"> (also meaning italic) instead.
Now, for consistency-sake, I've been changed the <span> tags back to <i> tags. But, that takes a looong time, since there can be 4-6 <span> and </span> tags in a single paragraph.
Anyone have any idea why this is happening? And how I can stop it?
