IReport: how to hide a line with text fields without a data line, contains various data

I have an empty text field (it contains a string or bigdecimal value) superimposed on one line for my report displaying an empty line.

To remove an empty row with zero rows, I used the property for the report items in that row. But that does not work. isRemoveLineWhenBlank

Can anyone help me with this?
