I don`t know where the errror might be - however, try another (better) design and start with R2 infinite.
As you can see, R2=20 ohm is extremely low in comparison to the other resistors.
More than that, because of the high Q-value, another variation of the filter structure is recommended:
Some positive feedback (resistive voltage divider to the pos. oamp input). For high Q values, this modification was recommended by Deliyannis long time ago.
Also in this case: R2 infinite !
As a consequence, this modification gives a higher midband gain - is this acceptable?
Hint: This MFB alternative is considered in some filter design packages - perhaps also in Okinawa`s program?
