There are a couple of applications and hardware devices I need to open a port for port forwarding on the Motorola Surfboard SG6580 but the port technically remains closed checking it with a networking utility although the configuration saved remains enabled with the correct local static IP and port number.

Is there another security option I may need to be disabling in order for these ports to actually open?

Do you have the devices connected and listening?  That's the only way they'll show as being open.  Some ISPs block all ports they don't support before they get to your router.  The Shields Up service from GRC can check to see if the ports on your network are listening.  https://www.grc.com/x/ne.dll?bh0bkyd2

I just checked both of my ISPs.  My phone company actively blocks incoming requests on most ports (reports as closed) and doesn't respond on 6 ports.  Comcast doesn't respond at all on any ports but 80 and 443 which are web server ports.

That does not prevent me from making outgoing requests but it does prevent me from accepting incoming requests on all but a limited number of ports.

The ShieldsUp service is stating that 100% of my ports are in stealth mode.  How do I disable stealth mode without compromising my security?

It's not your choice which is why I suggested checking it.  You probably have 'residential' internet service.  If it's thru Comcast, they won't unblock any more ports because they don't support anything more on residential service.  You would have to get a business account.  I know that you're allowed more on a business account but I don't know exactly what.
