Can you please share some screenshot of the issue because right now I am unable to see the extra tags you are pointing at, refer: http://prntscr.com/dvihdz
The em tag is not added by wplms theme, so it means someone has used the em tag but forgot to close the tab.
I checked your website and found the em tag unclosed, refer: http://prntscr.com/dwrhi1
Edit this widget and close the em tag.
