Google Maps API (Cloud Platform) How to change this text color using style editor (instead of JSON Array)?

Map preview at Cloud Platform Style Editor

When I changed the text fill color and stroke color it appears all fine on the preview Custom Maps editor, but when I applied the custom style to map-ID, and use the map-ID in javascript, the text color are not consistent; the POI has the expected color, but its business nature / type /or review rating has all different colors (as below)

At the moment I could only change their colors by using JSON array (instead of applying map styles to map-ID). Is there anyway to makes all text descriptions the same color?
