Set text color on DWG export

[leeUT3Y6]

Hello
When export Revit model to Dwg file, all text color are white, regardless of the layer it mapped to on the export setting.
The only way I can change the text color, is by setting the color of the text in the revit model itself.
I would like the text on the Revit model to apear in black color, and on the dwg file apear in green color. 
For all other objects it works fine by the export setting layers, but for some reason, for text objects the color on the dwg file is set by color and not by layer.
Am I missing something?

Thanks
Lee

Cannot map Text Type/Style in Revit. You can either use several Text Types with different colors/styles! OR instead of using plain text use something else to place notes example: keynotes which can be mapped

In the Export Setup, check the Export Layer Options and your Color ID settings.

• text within tag families (exported to blocks) may be locked as a nested item in the block too.
• you can also try selecting all the text int he DWG and make sure they are st to BY Layer.
