polypaint from texture>edit>New from Polypaint not working properly

Hello there, here is what im doing

-load my obj
-morph target
-sub div close to 1M
-switch Morph
-divideHD
-load texture
+polypaint from texture
-turn off texture map
*edit my polypaint
-New From polypaint ==== this just exports out the same unedited polypaint =====

i also tried multimap exporter (texture from polypaint)

is there a known bug, or am i doing something wrong? im using Zb4r5.

thanks
