Very possible some debris has lodged in your valving , forcing the shims to stay open and bypassing the valving function. A normal suspension service will likely get you an answer.

Those springs are made in two different lengths, depending on year and model. You may have gotten 465mm long ones when you needed 485. This would explain the discrepancy. How long are they?

Yours is 230mm of suspension travel, Std 05.5 is 210mm.

SE Stock Springs

STD SE are 5.9N/mm 450mm long

ADV springs are longer 465 or 485mm. Be aware.

Preload can be adjusted internally with plastic spacing to suit spring rate change.
