Convert/Upgrade Distribution Group to O365 Group


I've 3 DL Groups that I want to convert to O365 Group. I can see an option says "UPGRADE DISTRIBUTION GROUPS" but can see only one DL Group not all three... why so?

Waseem not all DL can be upgraded to groups, please see this document about the ones that are not eligible (see "Which distribution lists can be upgraded?"):
