I did not find any posts about it, so I decided to create one.

The missions took with Preston Garvey to clear a settlement and install a radio, someone kidnapping , and others have an end? I've done several missions of the same style and Preston Garvey is still giving me other.

Help me

No, just ignore him. It will pop up constantly. It just stays in your quest log, you just don't have to do anything about it.

His missions do end but settlement missions from minute men radio you get later do not end.
