Based on your Task History, we can see that before the first execution of your workflow, you had set up only 2 steps in your workflow: Facebook and Gmail. Therefore, you received a lead, and an email was sent to that lead through Gmail.
Before the second execution, you had set up 3 steps: Facebook, Gmail, and ClickSend. So, an email and SMS were sent to your lead.
Before the 3rd and 4th executions, you had set up Facebook, Gmail, ClickSend, and Google Sheets steps. Therefore, an email and SMS were sent to your lead, and also the details were saved in Google Sheets.

Going forward, all your Facebook leads will receive an email, an SMS, and their details will be saved in your Google Sheets, unless you remove those steps from your workflow.
