That's Sim results, or real results?

the Opamp Supply rails are not connected on your schematic though. You must use a dual rail voltage (+V, -V)

What available voltage rails you have available on your board now? (regulated and not regulated)

One thing is sure, as the OPamp pin 2 is considered as Ground, i would use higher value for R4, R5 to don't interfer the Pots impedances.
