Hi, TheDeliveryBoy,
This sort of problem shows up often from people who have done traditional art, or those moving from "paint" like programs. I would suppose everyone doing art has some experience w. "coloring -books." B&W figures made of outlines that can be filled w. some sort of pigment. And, as one progresses, one starts drawing ones own outlines. So most everyone comes from a background where one makes an outline, and then fills it in.
Vector work is sort of the opposite. One makes the filled area, and then can put an outline around it.
To get the effect you want with the "W" in your example, use the pen or pencil tool, and draw the letter shape. Use the "fill" dialogue to give it a color. After you have made the filled shapes, you can then use the pen or pencil with a thick stroke to draw the outlines. Those shapes can then have pixels "paint" put in them. See my quick addition to you test.

Hi The delivery boy,
Welcome to the forums
This is because your letters are currently made out of a few small open curves instead of one closed curve. I will include a video below showing what I mean. Unfortunately I don't have a mic so I can't add voiceover.
Thanks
Callum
