This is very much a role of the dice.
All of these eyepieces are identical with different brands and paint jobs.
I have a Yosoo branded version of this eyepiece that doesn’t do what you describe, but it’s also not as sharp as the 9mm Corvus Optics branded version I have.
For the price these eyepieces are sold at, my guess there is little to no QA. Maybe Agena has a contract with the maker for minimum QA, but I doubt that QA involves a factory field test of the eyepiece.
