Additional space in Previous comment field of HCM form

Hi,

We created a process using HCM from and process framework and archiving using Opentext.

When forms open in portal there is no additional row space between  Previous comment field  row,but after archiving when forms open using tcode J6NY in R/3 there are additional row space are there in previous comment field.

So there is any possibilities to remove this extra spacing which coming in previous comment field.

Thanks,

Niti
