This upload is pulling the wrong info

The contacts reflected and the quantity its supposed to upload is from the wrong document. It's not pulling the correct information and is uploading contacts that I don't want to upload. No matter what I do it is adding people I don't want to upload at all. I tried creating a different worksheet and uploading that one but it keeps uploading the same sheet. . . This is annoying and I can't use the upload function now. . .
