OK, I see the problem you are having.  It seems to be a bug with the GUI.  To get around it do the following....

1.  Make the change to "Permanent" to add port 1900 as TCP.
2.  Assuming you are using the "Public" zone then edit /etc/firewalld/zones/public.xml and change tcp to udp
3.  Then do "systemctl restart firewalld.service"

Give that a try and see if it works for you.
