[amibroker] Export data and AddToComposite fails on Renko chart

[DStricek12]

Hello,

Im trying to export Renko data values based on GSPC (SP500) ticker. 
The Renko  chart is displayed fine. 
The problem is that exported   renkoquotes.csv file  contains empty values. 

Next    I have    tried  AddToComposite and it  fails to load Renko values  in 
composite.

Does anyone  have clue why is this happening?

Any help would be appreciated how to solve this.
