Different z probing points for dual e3d v6

Hello, so I'm having an issue with Marlin and dual extrusion. I have two e3d v6 extruders with nozzles 27mm apart from each other (on x-axis). I'm using Cura 3.3.1 and have my offset in there. I'm using a bl touch smart as my z probe. I've noticed that when I try to print with my second extruder that the printer homes at different points on the bed. These points also happen to be off of the bed. Does anybody know why Marlin would use different probe points for different extruders? It seems unneccessary to me as long as it knows the offsets. Thanks for any help.

You are using Bi-linear Bed leveling, though you have not enabled any boundaries.

// Set the boundaries for probing (where the probe can reach).
//#define LEFT_PROBE_BED_POSITION MIN_PROBE_EDGE
//#define RIGHT_PROBE_BED_POSITION (X_BED_SIZE - MIN_PROBE_EDGE)
//#define FRONT_PROBE_BED_POSITION MIN_PROBE_EDGE
//#define BACK_PROBE_BED_POSITION (Y_BED_SIZE - MIN_PROBE_EDGE)

Thanks for replying. I'll try that out in the morning. I think its weird that marlin wants to probe different positions for the second extruder but if it works it works.
