The position of the filament reel holder and run out sensors do not align. The printer is setup for 500kg reels.  
Any suggestions on how to resolve?

Three suggestions:

1. Unplug & remove the sensors.
2. Change spool for left extruder on right holder and vice versa.
3. [Print sensor mounts that fit your needs.](https://www.thingiverse.com/search?q=sv04+sensor)
