Select first line from datastes (Text manipulation)

1

Hi everyone I would like to ask you the opinion that can help me to overcome the little problem that I am facing. Once I use Select first lines from datasets in Text manipulation tools, I set up to select 100 first lines and extract it from my datasets. Even though I have set up 100 when I get the result it again shows me the first 10 lines which are default set up of this tool. I have tried many times to change 10 to different numbers but it did not work. Every time I get the first 10 lines result as a default parameter. Could you help me with this issue?
