Probably the range of the trimming potentiometer P18 (- adjust) was not
sufficient because P18 and R94 are connected in series. The effective value
of R94 (normally 22k) has been probably reduced by soldering a second
resistor in parallel to obtain the correct adjustment for P18. But I don't
think that the additional resistor is 10k because this would result in about
6,8k which is totally different from the 22k. I cannot imagine that the
value for R94 is that far away from the correct value for the P18
adjustment. I'd expect a higher value for the additional resistor (in the
47k...100k range).

I'd not recommend to remove the resistor as I think it has been added
intentionally.
