Thank you Lowlander and MiPi!
That helped me. I didn't know of klicking search button.

Also if you remove the Lyrics from the Lyrics tab in Properties and search again the next Lyrics source will be searched. Repeat till you get a working version.

The problem is not on MM5 side, the mentioned lyrics are inserted incorrectly to original lyrics servers. Try just go to Properties - Lyrics tab and press search button again and again (next press tries next servers). Or you can try to select different lyrics servers in Options - Library - Metadata lookup. It seems in this case some lyrics on ELyrics and Song Lyrics are incorrect.

You can remove the Lyrics and do the lookup again. It seems only certain Lyrics sources cause this issue: https://www.ventismedia.com/mantis/view.php?id=18916

I attached a screenshot of lyrics from famous singer Lara Fabian in french.
There are a lot of wrong font codes in it.

How can I fix it?
