Action Descriptor layerKind different to object dom kind?

Hey

Perhaps some1 can help me out there.

I'm trying to figure out why action descriptor result is different to dom, or how to get the same result?

my results:

ActDescr : 

{"id":3,"name":"Brightness/Contrast 1","kind":2}
{"id":4,"name":"Levels 1","kind":2}
{"id":5,"name":"Curves 1","kind":2}
{"id":6,"name":"Exposure 1","kind":2}
{"id":7,"name":"Vibrance 1","kind":2}
{"id":8,"name":"Hue/Saturation 1","kind":2}
{"id":9,"name":"Color Balance 1","kind":2}
{"id":10,"name":"Black & White 1","kind":2}
{"id":11,"name":"Photo Filter 1","kind":2}
{"id":12,"name":"Channel Mixer 1","kind":2}
{"id":13,"name":"Color Lookup 1","kind":2}

{"id":15,"name":"Posterize 1","kind":2}
{"id":16,"name":"Threshold 1","kind":2}
{"id":17,"name":"Selective Color 1","kind":2}
{"id":18,"name":"Gradient Map 1","kind":2}
