Missing harp support shims?

[Wavedude]

Hey, my 88 key mk1 has 2 shims supporting the left side of the piano harp and only one thinner shim on the right side. Is that normal? It makes the harp look uneven as it sits on the rest of the keybed.
And the reason I'm concerned is because I think this might have something to do with the higher notes choking out because of the uneven escapement.

It is normal to have thicker shims on the bass side,but yes, this can be the cause of your problem. I would be sure your escapement is set high enough in the treble but leave thicker shims on the left.
