TLV2771: Drift/Offset

Part Number: TLV2771

So, I got this circuit, my sensor is a piezoceramic disk and I use small round ball of steel to impact the piezo.

The problem  is when i connect the OpAmp the signal is offset and this offset increase with multiple impact.

I just dont know why this happen and how to solve that.
