How can I remove data for a day from Garmin Connect?

Between 7-13 March I wore the watch only a couple of hours at the end of the week. I was stressed during that timeframe so now the whole graph isn’t really accurate anymore as it shows a huge spike. How do I remove data for that day (March 13)? I wasn’t wearing a watch the rest of the week because it was defective and I was waiting for a replacement.
