[VE][79] End tag for element CENTER is not open?

It says that a leftover end tag is caused from an element that was removed during editing. Look at my HTML code. </center> is there.

<h1><center><font color="#ffffff" face="verdana" size="5">This Is My Personal Testimonial of The Scar Revision Hair Restoration Transplant Surgery I Had Done On<br>
