is it me or the practice notes in 30 days beginner 1 low voice notes is missing ? 

That's correct. As mentioned elsewhere, the beginner lessons for low voice with John Easterbrook are missing almost all of the associated content. No audio-only warm ups, no lesson notes, no song sheets, no song audio for practicing. These things have been asked about for weeks or longer and nothing has been done to fix it.

Hopefully someone from the web team will follow up; I'm sending this thread their way!
