YouTube converting layout issues

If I convert the following file to youtube. The first and second lyric lines float into each other.
Layout in musescore and the upload on musescore.com is fine.
There seems to be some issue with breaks.

Is there any rule to follow to prevent youtube convertion from mingling mix everything up?

Here´s the youtube link:
