Using two op-amps as voltage followers, one of them does not load the input signal, the other one does- see the figure below.
The signal at inaP3_3 (port P3[3] ) is fine, no problem. But at inbP0_2 (port P0[2]) , the AC component is removed and I only have the DC portion of Vin (1kHz, 0.5Vpp with 0.3V DC offset). At lower frequencies I start to see more AC component. As if there's a cap on the input.
I'm using the CY8Ckit-059, so I checked the schematic and did not see anything connected to this pin.
Can anyone suggest how this could be happening?

It seems it was already:
If you have CY8CKIT-059 and you have not deleted C12 (P0.2) then this is the problem.

You will have to either delete or use another contact.
