Stabilizers issue

Hi all,

Seeking for your assistance on this issue i found. So this 3-months old Huntsmen TE is been great and I love using it. However, I encounter a problem when i recently change the key caps to the mercury white. The stabilizers is kinda stiff (based on my speculations) and here is a short video of it.

=> It's is kinda short, but when I press the shifts/backspace it has a weird sound and cannot be pressed fully not like the spacebar and enter

=> Old problem when i change the spacebar. It was stiff and the same goes to the enter, but i got it fixed when i change the stabilizers. However, I did it to the other keycaps that needs stabilizers but still same old problem.

Right now, I'm thinking of lubing them (could fix my issue...not sure yet) and putting on some foam (to mostly remove that rattling sounds because I hate it) like on this video() but still thinking that if this could void my warranty if I open the keyboard.

Thank you all in advance
