Beginner question about preset management

Hello, this might be related to FlowerP’s issue:
I’m also having trouble importing projects on the presets page. I’m trying to upload the Prophet 08 project from this thread but after I hit the upload button, the pop up window disappears and nothing else happens.

Also, I can create new presets but I can’t delete empty ones for some reason.
I’m using an Intel Mac / Monterey OS and the latest version of Chrome.
