The subgraph has become a complete mess.

### Prerequisites

- [ ] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

1.Cannot correctly name the port.

2.Incorrect connection point

3.Unable to display the widget correctly.

4.Even once, for some unknown reason, the internal data became completely chaotic. For instance, in the subgraph's KSampler/Checkpoint Loader, all the data changed.
(No screenshots, but it does exist......)

### Steps to Reproduce

1.It was there all along, quite obvious.
2.It was there all along, quite obvious.
3.It was there all along, quite obvious.
(How did this version come to be released?)
4.I made several attempts to make my subplots display normally(Including restarting ComfyUI, constantly renaming the "port", and constantly showing/hiding the input.). After copying the subplots across different projects, I found that the internal data was incorrect. Both sides were wrong, whether it was within the project before the copy or in the project after the copy.(I'm not sure about the timing when the data changed. I only noticed that the data had changed while the program was running.)
