SP Multiline text column adds site owner name for every record added

Dear Team,

I have created a list to record Risks which contains a column of Multiline text type. After that a Flow will start sending approval request to different teams for every new risk added in list. Everytime risk is approved or rejected, Flow adds a record in Multiline text column with approver name. 

Problem is for every entry in Multiline text column, flow also adds my name along with date and time. I want to avoid it. Not sure why it adds my name every time in multiline text column. Pls see attachment. The name highlighted in yellow is my name for every entry added, I want to avoid it. Please suggest way ahead.
