Transparency was the problem.
Text should be already transparent on its own. Outside of that you need to find resources that are already in PNG format without the background. Otherwise you will need to do it yourself and paint.net most def is not the program to use for that as you waste a lot of time due to the lack of tools it has for background removal.
Paintshop Pro is actually decent and less of a hassle to use than Photoshop, though photoshop is an industry standard but I hate how adobe went to the subscription type of plans for the newer versions. Where Paintshop Pro you can still buy it standalone from the site. Not cheap, but its good for graphical work.
