Problem inserting symbol after creation using Autoplant V8I 64bit

I have followed the steps and taken the existing gate valve symbol to modify and elongate it into a different symbol. I went through the necessary steps and when I insert from symbol manager into the PID it doesn't fully trim the process lines out of where the symbol is inserted. The text is not centered to the new sym, instead its centered to the parameter of the gate valve pre modifications. Not sure where to go from here to fix this problem. Any suggestions? Thanks.
