Loop saves results in number of csv files instead of one, help needed please

Hello;
I am new to Kantu and don’t know about scripting, try to learn,
from the examples of inbuilt macros, I tried to make a script from these examples and it is working, but some part not working the way I want to:
The script search youtube with keyword pulled from csv file, then save some text from different places of found results into csv file, I want to loop it, it works with the loop button on Kantu,
but when I loop it let’s say 10 times , after working all 10 loops, it save the results to 10 csv files,
so I have to delete 9 csv files because only the 10th. csv file have the complete info.
I am not sure how to code the right way.
any way to make it write to one csv file only.
appreciate your help.

here is my code:

  "Command": "open",
  "Target": "https://www.youtube.com/",
  "Value": ""
  "Command": "click",
  "Target": "name=search_query",
  "Value": ""
  "Command": "csvRead",
  "Target": "ytSearchKw.csv",
  "Value": ""

  "Command": "type",
  "Target": "name=search_query",
  "Value": "${!COL1}"

  "Command": "click",
  "Target": "id=search-icon-legacy",
  "Value": ""

  "Command": "storeText",
  "Target": "xpath=//*[@id=\"keyword-score-mount\"]/div/div[1]/div/span[2]",
  "Value": "c2"

  "Command": "store",
  "Target": "${c2}",
  "Value": "!csvLine"

  "Command": "storeText",
  "Target": "xpath=//*[@id=\"keyword-score-mount\"]/div/div[2]/div/span[2]",
  "Value": "c2"

  "Command": "store",
  "Target": "${c2}",
  "Value": "!csvLine"

  "Command": "storeText",
  "Target": "xpath=//*[@id=\"keyword-score-mount\"]/div/div[3]/span[2]",
  "Value": "c2"

  "Command": "store",
  "Target": "${c2}",
  "Value": "!csvLine"

  "Command": "echo",
  "Target": "${!csvLine}",
  "Value": ""

  "Command": "csvSave",
  "Target": "YT-info6",
  "Value": ""

  "Command": "localStorageExport",
  "Target": "YT-info6.csv",
  "Value": ""

So it creates 10 different CSV files? What names do these files have? I see only one name in your macro, YT-info6.
