You still have a problem.  Swapping relays didn't solve the problem but helped diagnosing it.  Relay contacts work with contacts in the pod to form the circuit.  All contacts acquire a thin oxide film and when presented with voltage the film hopefully burns through but not always.   The combination of poor contacts gave different results. In a short time they will fail again.  It would be best to clean the pod contacts and change the relays but the easiest way is to only change the relays.  

But let this be a warning to change ALL your relays, not just this couple.  I've used WayTekWire for mine, there are many sources. 
 

Problem solved. I only had to switch the relays like many of you suggested and Voilà! Problem solved.

Now my question is: How come this solves the problem ? Why is the right side not going up and down endlessly when its relay was on the left side ?

There must be a logical explanation somewhere. Please don't think I can't handle the truth. Ah! Ah!
