Hi @Cait-M,
Absolutely not a silly question, thanks for posting!
I would recommend creating and syncing to a new project with the correct name exactly as you suggest, as Jon says in this post.
To do this correctly, it’s probably easier to save the new version of the experiment file in a brand new folder and then push to Pavlovia from there. This avoids you having to delete hidden git files etc.
Hope that helps,
Kim
