This isn't a big "issue", but I'm wondering how to move the actual application to the desktop, and not its alias (I'm "OCD" and don't want those black arrows on the bottom left hand side of the screen).
A picture is attached to clear up my inquiery (BOTTOM 2 icons).

The arrows simply indicate that the icon is an alias. Remove the application alias, then locate the real application in your Applications folder and drag it into the Dock. BTW, that is the Dock, not the Desktop.
FWIW, the arrows do nothing harmful. They are there to inform you that the icon is an alias that was dragged into the Dock. Arrows or not all the icons you see in the Dock are aliases. The others simply don't have the curved arrow.
How to erase desktop icon arrow?
