DR4088LN-CS with DR4088CS some of my sensed blocks activate with just a touch of the sensed wire


 

I have just discovered after adding additional blocks that some of the track when just the sensed rail is touched with my finger it will activate the sensor and generate the message of an active block.
?
What I discovered is when metal wheels on the cars cross the insulated jointer between what is the active block where the engine is and the block no longer occupied by the engine.
The previous block would activate because of the metal wheel on the car.?
?
Has anyone seen this before the single rail activation and is there a solution??
?
I insulate both rails between blocks and run the pair of feeder wires back to the DR4088 for sense and a collocated terminal block for the non-sensed wire.
My main bus is 14 gauge and my drops are 20 gauge. Drops are a few inches to maybe max of 4 feet.
DCC voltage measured with a RRAmpmeter is 14.2 volts on one booster and 14.4 on the other . This is for ho.
?
Thanks for your help.
