It's normal sort of, but also indicative of too much lube. Reseat the spacebar a few times and see if it helps, but while the spacebar is unmounted check the stabalizers clip to the plate. Since it's plate mount, pretty much every time you remove the cap there will be a small chance something gets pulled askew.
Press the housings surrounding each stem on either side of your stabalized caps down while keeping pressure on the bottom of the board, and listen for any small clicks.
If it's still happening after the checks, take a decently long video of the stabs both with a cap mounted and without, and we can help more.
