anim particles and fire + smoke

I got 2 files with some anim cycles or Opengl in viewport
1 - file with particles along a path curve

and it works fine for anim cycles or Opengl in viewport

2 - file for fore + smoke
anim works fine

now if I copy all the fie + smoke object to the other file

the fire + smoke does not work well at all
looks horrible

smoke goes up only 20 % of the height in the other video for some and fire alone!
and fire is not looking nice !

what is going on here and how to correct that ?

thanks for any feedback

happy cl
