A problem with DC-blocked filter

$

Hello.

I performed a simulation of filters, When I simulated a lo-pass filter, the results was correct. But, when I tried to simulate a band-pass filter, with a blocking capacitor in front- the results seem incorrect(I compare to LTspice simulator).

I addition (maybe not directly regards that problem), when I checking the current in the ground pin of the opamp- its value is several amps, when the real value is about 1 mA( the other currents, including the power supply currents) seem correct.

I can't attached the file due to our "firewall" security, but I can send it by mail.

Any suggestiopn?
