Without seeing your circuit, I'll have to say you have a/some wrong part(s) somewhere.\

I don't know how you expected to get a useful reply without your schematic diagram.

Your input swings above and below ground (0V). Your op amp outputs can't go below ground. You need to use a negative supply for Vee, or you need to bias the input signal up to Vcc/2 by capacitor-coupling the input signal into a voltage divider on the left end of R5.
