Side sensor base part change

Hi, 
I am assembling a Core One+ and got to the side sensor.
The one that I got seems to be different than the one shown in the assembly manual at page 163: https://help.prusa3d.com/wp-content/uploads/generated/prusa-core-one-kit-assembly_2251_en_2026-01-10.pdf .
There is no slot to insert a second magnet (see red) and it seems the distance between the ball and the magnet on the lever is larger that shown in the assembly manual (see blue). As a consequence, the ball is not attracted to the magnet.

Please advise on how to proceed.

This holder is used in the CORE One+ extension. And you should have a small orange part into which you insert a magnet. And you insert this part into the holder. If you do not have it, contact Prusa support.

Also be careful that the magnet in the lever does protrude out too far or it will bind the lever to the cover.

Yes, I actually had that problem during the initial checks when I was asked to insert the filament and it would not pass through. So I had to disassemble the sensor. But now everything's working.
