Mparn:
I have no idea what your original circuit was before changing to LEDs.
This happened when we changed the fixture over to led. Each fixture had the option to use either switch (each fixture had 2 switch legs, we capped off the one we didn't use).
Lighting is normal
This is an incomplete description for me to follow.
I don't know what your background is, but I don't think you have studied the field of logical circuits.
What Larry and I think your circuit is can be drawn on paper as:
At the left draw a circle with a one cycle sine wave in the center. This represents your AC voltage source.
From the top of the circle draw a line up some ways. Label it Hot.
From the bottom draw a line down some ways. Label it Common.
From this common wire draw a horizontal line to the right across the page.
From the top hot line draw a horizontal line a short distance and place a SPST switch and label it A.
From the right hand side of A place a light between A (output side) to Common. This is light A.
Also from the output side of switch A continue with a wire to the input side of a switch B.
From the output side of switch B place a light to Common.
This is the circuit Larry and I believe you have.
To correct this problem you want to move the input end of the wire to switch B to the input end of switch A. Then the two switches will be independent of each other.
