I imported songs from our EasyWorship 6 into version 2.4. When I exported them to a directory then imported them into my laptop so I could add the page numbers to them I noticed some of the import data was not done correctly in the Authors area.
I tried to export them as a test, the ones that had numbers or symbols. They return a syntax error which stopped the export of the songs on the song that had the symbols or numbers problems.
After i removed these issues the song then exported correctly.
