We’ll have to pass that on to the team later, but I did just test it and I want you to check for yourself. On my Desktop I verified if I clicked Save, it would go away and nothing new would be added.
HOWEVER
If I type in everything and then hit Enter on my Keyboard instead of clicking on Save, it would add it.
Are you on Desktop as well? If so, can you try as I mentioned and see if you have any troubles?
