Thanks for reporting these!

For the dropdown, is it a D.T field (like a field from the contact record) or a custom dropdown you added to the form? And what are the first couple of options in the list?

For Safari, would you be able to post a screenshot of what you see? It would also help to know if anything shows up in the browser console, or in Utilities (D.T) > Error Logs.

Let us know what you find!
