Wood does soak at different rates. Add a few more coats and it should even out eventually.

Ditto all the above. I thin my initial coats so they will do that intentionally and keep adding at knots and other places that soak it in. As long as I keep it wet, I can keep adding to those spots. Then I let it harden and work the finish until I’ve built up enough coats to sand (e.g., 600 and water or oil) and polish (e.g., using a Porter Cable ROS-Polisher and microfiber cloths on a hook and loop pad dabbed with swirl mark remover or auto paint).

When done, no one knows if the project was brushed or shot.

More coats of finish, sanding lightly between then is one way. Then when it has cured (about 3 days) you can lightly sand with 400 or 600 sandpaper to remove any fine dust bumps. I like to apply a paste was with white 3M pad and buff.
Applying it with a sponge brush may leave bubbles as will brushing or working the wet surface too much. Be generous with the application and try not to work with water base when the ambient temperature is over 75….65-70 works best for me. When it is warm and or low humidity the water base finishes start to cure before they level out.

On porous woods I often pre-coat it with a coat or two of de-waxed shellac in a 2# cut to seal the wood. Shellac drys in a very short time (at 70 degrees about 30 minutes) so it speeds up the overall time. It is easy to apply it with a clean soft piece of cotton cloth….wear gloves to keep it off your hands. If you use a brush clean it with household ammonia and warm water. Zinsser’s Sealcoat is one source of a de-waxed shellac that works well. Note: it must be de-waxed or the poly top coat may not adhere well.

Everyone, I appreciate the feedback and the knowledge. Thank you very much. Not quite there yet, but it’s getting better with the more coats I add.
