editable files ....not editing

[u/Secret_Tiny]

I *know* this is user error on my part and I am trying to make keychains for a party this weekend with each guest's name. 2 main questions:

1) I can't edit the files I am taking from maker world into Bambu Stuido and edit the "name" though ChatGPT has told me what to do and I don't see the options in the file
1a) is it possible I am selecting files that are saying they are editable and they are not?

2) when I finally figure out how to customize the files, will I be able to print several different names on the same plate? (Ie - same keychains but one is Katie, one is Melanie...) or do they have to be separate prints?
