Wrong Extruder Responds

[RobinAnneF]

At this point my experience with my A10T's extruders is as follows:

I select to change filament on extruder 1 - The printer unloads extruder 2
I select #1 a second time - The printer unloads extruder 1



I have updated the firmware a number of times (when ever I see that Vert has updated files)
"Verts-Marlin-verts-bugfix-2.0.x" - https://github.com/Vertabreak/Verts-Marlin

I suppose, what troubles me most about this issue, is that I rely on the printer knowing which extruder it is to use for color mixing. It continually fouls up my intended color choices

I believe this is a firmware issue, but I am too new at this to be certain. Any help would be greatly appreciated....
