Spacebar and enter key of mine is like that.
What I done is
Blow with hot air (soften the key) using hairdryer to the key, then adjust slowly in.
Do not force the key fully in. Adjust slowly in..
You will reach a point where the key bounce like other keys. Then when u satisfied only stop.

My finding is the key is slightly concave, compared to normal.

So, the key experienced high downward force than upward.

Oh, so your problem actually boy with the stock stabiliser or stock keycaps, but the extra RGB?

I means the problematic keys are with the extra RGB, but not on the original white keycaps?

RGB ya red green blue yang blank ya. Ya nama nya modifier. Stab ya cherry stab. Stock ya stock keycaps. So, which one yang bermasalah? Hehe...

No wonder they feel different than the stock keycaps. It's double shot. Is it something like this:
