Sigil will not generate role or data-docx-vert attributes. Those had to come from somewhere else. The last looks like it might be xml from a Word document. But regardless, I don't think they're epub spec compliant. The solution is to remove the two attributes and their values. Use spans and superscript css to accomplish what data-docx-vert="sup" seems to be trying to achieve.
Somewhere along the the line, a docx to epub conversion is leaving non-compliant markup behind.
