Thank you for checking that. What you are saying is essentially that the resistance across R9 is 11K. The power was off when you measured this, correct? Can you please double check to make sure R9 and R10 are really 100k.
Also, please turn all the dip switches to the off position and re-measure the voltage on the opamp pins (when the power is back on).
Other than these things, please use your magnifying glass to look for little solder balls or other things that could cause shorts on (both sides of) your board.
Let me know about R9 and 10. If none of these things solves the issue then you might want to move towards replacing the TL074.
