How to setup E1 / X2 with TMC2130 (no replies)

Hey guys and girls, I am curently gambeling arround with more TMC2130 Drivers, its only on the Bench but maybe you could follow me:
ich got TMC2130's including SPI and DIag0 on all 6axis (on my new printer this will be XYZ X2 E0 E1 XYZ are working fine, i know how to asign X2 etc thats not new,
but on TMC2130 Debug M122 I ony get status reports on XYZ never on X2 or any of the extruders,
If i set current via
SENDING:M906 X I1 500 // it always reports (like it would work) back current of all the other axis, but not of the "uncommen ones"
X driver current: 800
Y driver current: 900
Z driver current: 900
This is M122 output:

Driver registers:	X = 0xE0:0C:00:00
	Y = 0xE0:0E:00:00
	Z = 0x80:0E:00:00

could someone tell me if ther is just not feedback on this (X2 etc) or am I mistaking somwere?

btw tm2130 lib is form 5.8.2018 so thats new.,
