Pushissue Plane() has been cause by user error it's been fix,
After I figured I was using wrong services trucks for those medium plans for J1 I believe, I wish the tutorials will explain or be more improve on. It can be confusing which services trucks are use to re-route your big plane it is a steep learning curve I felt stupid I used wrong pushback truck by mistake. So the last one was not to much of a bug it was myself using wrong stuff. Also I like to added in some Staff Rooms drop down menu with Select or De-Selected are not really working ok.
