Cross section > Place Cell/Block not working

I have created Cross section successfully using various styles . Now i have to place a Cell on alignment for annotation using PLACE CELL/BLOCK tool, but its not working. 

I have selected the Cross section set and filtered the horizontal alignment after this in Data section there is a object  Called cell / Block in this i have selected a cell and apply but it's not showing in Cross section. 

Please suggest me any possible solution. 

i'm using POWER RAIL TRACK V8i Version 08.11.07.428
