Issue with color and font with ofxFTGLES

Hello
I try to do a text wrapper using https://github.com/fishkingsin/ofxFTGLES.
the wrapper is positioning every word separately in order to change weight or font style anywhere in the block of text.
please have a look here: https://github.com/paul-ferragut/ofxEasyText

I’m stuck with an issue, colors are not responding anymore once I draw the block of text.
Let me know if you have a hint.

Thank you

It seems that the issue come with FTTextureFont.
swapping FTTextureFont with FTPolygonFont fix the issue but FTPolygonFont is not looking pretty.
Is it some buffer issue with FTTexture? I’m not sure what to try to debug it
