I have purchased this year ago and I love it. I have updated my use of this product but when I put the date on it it does not replace the picture, it adds a second picture with a date. Is there something I should be doing to replace my photo with the same picture except I now have a date on it. I don't want 2 of the same pictures, with a picture with no date and another same pictures with a date. Please let me know what I am doing wrong.
