Change Filament fails

Why does the direct filament switch over DWC

fail with this error:
Error: M701: Unload the current filament before you attempt to load another one

When I first unload and then load it works

Here are my macros

I still could not find a solution?

DWC sends the following code:

T0
M702
M701 S"GreenTEC black"
M703

After unloading comes this error:
Error: M701: Unload the current filament before you attempt to load another one

Does nobody else have a problem with that? (Affects only the direct filament change via DWC)

Chrishamm is the expert on both filament management and DWC, so I have asked him to reply.

To me it looks like M702 completes before it is actually finished, so M701 is called out-of-order which generates this message. We will investigate why this is happening.
