Ah, okay. Those "DIRECT" on rpt1 and rpt2 on your 2820 means you using "Local CQ" in your To field. You should be using the Repeater->Use Repeater CQCQCQ on your 2820. And you need to make sure that your From hot-spot setup is using either DUP+ or DUP- with a zero offset, otherwise your 2820 will revert back to DIRECT. I've never used a 2820, so I'm not sure of the specifics for that radio.
On newer Icom radios there is a "Call Sign" menu item in the main menu that will show you UR, R1, R2, and My so you can see what will be in your header packet.
qngateway is suppose to automatically fix DIRECT repeater entries in the header packet, but I see there is a bug in it, so it's not working for you. I pushed up a new qndvap version that should fix this, but you should properly configure your 2820 to use your dvap properly.
