Change stream on parcel

[rkgddg]

Hello everyone. I am Manager of a parcel, the parcel was set to Group and the owner is my boss. He gave me rights on land and it is all set on group. But I cant change stream on parcel and I have the rights of it. I have check it and even with group tag I cant change it. Someone know why?

"set" to group doesn't enable most of the group-powers as shown in the group profile, the parcel has to be deeded to enable those
