LibreOffice Writer, ver 4.4.3.2, english, using table function. How do I get rid of yellow and underlined text used in strike-thru feature?

After using the stike-thru feature, I can’t get rid of the yellow underlined text. Everything I try to type appears yellow and underlined. How do I get back to normal type? Underline and highlight features are turned off.

I had the same problem, and found the answer elsewhere- you’ve accidentally triggered Record mode; go to Edit > Track Changes and uncheck the “Record Changes” options.
