Filament change with multiple plates doesn't work

[drumbo]

I have a project with 3 plates using my X1CC and PETG loaded into slots 2 & 3 on the AMS, each plate contains a single object. If I select the object on plate one, go to the layer height where I want to change filament, right click, change to filament 3 (object is set to use filament 2) I can see the little grey line appear on the height bar (indicating the filament change), the filament change times increments from 0 to 1. When I reslice the file I don't see the colour change in the object in the preview window and if I export the file to gcode I don't see any M600 change. If I search for the z height where I made the change - I can see no indicator for a filament change. Printing the file results in no filament change. Here is the first bit of g-code where the layer height changes to 5.2 (where I made the filament change in the slicer) (bold bit is my addition). Note that if I add a filament change on any of the plates - the slicer indicates that it is done, but the preview shows no colour change. Nor does the file print with any layer change. See image for example:

I have also noticed that a filament change at a set height seems to affect all plates - not just the currently selected on. Not sure if this is meant to happen, and possibly could be the cause for the issue above.

I actually notice that Filament change times registers as 1 just because I am using filament 2 as a starting filament as opposed to 1. Therefore it seems that although the grey line on the layer height bar appears after I have added the filament change - the actual filament change doesn't occur. If I start a new project, add just one object to 1 plate - the layer change feature works ok
