Artboards are linked to home, but greyed out artboards when sharing

Hi Anne-Novi,

Thank you for reaching out. By any chance, do you have overlay applied to the artboards? To understand the situation better, I would need to take a look at the file. 

Would it be acceptable by you to share the file for investigation? If yes, please upload it to Dropbox and share it with me via private message (Go to my profile, click on send a message button). You may also invite me to the document. I'll share my email address with you in a private message. 

Thanks,

Atul_Saini
