This has already been explained to you, but I will repeat for emphasis.
If you insist on prototyping by ear with an analog circuit, cease and desist with the solderless breadboard, especially if you do not have a decent fluke meter ($200) with accurate capacitance readings.
In a solderless breadboard every common bus are plates in parallel, especially the ground/power busses which are long plates in parallel.
See below:
Plates in parallel is the definition of a capacitor.
Design a prototyping board with socket terminals (see harwin/mill max) Swap to your hearts content.
Analog circuits is an art form and right now you're being a masochist, your circuits will never be repeatable.
