Coolant recovery tank on fender

Did you say you're filling it to different levels?
...is there coolant in the tank when your engine is cold?
After filling it, a few times of driving it the coolant level settles down below the empty line. That's the level it settles at when the engine is cold. Doesn't matter if I fill it to the top, half way, full line, eventually it levels out below the empty line after just a few times of driving.

That coolant goes missing all over that side of the engine bay and onto the ground.

With my much larger size coolant recovery tank none of this occurs.
