Default Potentiometer in Andante 1462. Original?!?

Hi!
I have this set Telefunken andante 1462. I decided to repair it since I’ll be waiting for replacement material to my previous repair.
Despite the set seemed to have not be touched previously, I find the volume/tone potentiometer to be faulty. I realized that it is a 2 x 0.5Mohm potentiometer with only one control axis. According to the schematic it should be a double axis control with 0,5Mohm for volume and 1.3Mohm for tone, am I wrong?
Does anyone find the same in this model.
But my main question is: why does R19 (1.3Mohm) have four leads in the schematic? Because the potentiometers i’ve seem only have 3.
Image with partial schematic with R19 is attached.

I was planning to replace it with one potentiometer from one telefunken jubilate 1161, but now I am confused in how to wire it...

Any help will be much appreciated.
