Delete weigh in but it keeps reappearing

I have a day where there are two weigh ins only minutes apart, I must have stood back on the scales by accident. I use the Index S2 scales for my weigh ins and have tried to delete the incorrect weigh in on Garmin Connect on the Android app and also on the web page. The weigh in deletes initially but returns later on. Is there any way that I can delete this permanently? I don't know if it's resyncing from the scales but am unsure how to delete it from the scales memory. Thanks for any help.
