How to update OPPID pipeline label?

Hello All,

I found the only way to update OPPID pipeline label is to browse and select new pipeline tag, otherwise the existing old pipeline label won't update, and if place new label, the old tag number shows still. Is it a bug? For equipment, if I revise the area/service, the equipment label will be updated immediately. 

Another problem, if I updated the piping tag, the piperun won't updated automaticlly. The piperun label is not same as pipeline label. Can it be fixed? 

Thanks a lot!
