By the nature of your question, your Elements 13 is not Premiere Elements 13/13.1. It sounds like your program is Photoshop Elements 13/13.1 (photo editor) and not Premiere Elements 13/13.1 (video editor). Somehow your thread got posted in the Adobe Premiere Elements Forum instead of the Adobe Photoshop Elements Forum.
If this is the case, please re-post your thread in the Adobe Photoshop Elements Forum or wait for a moderator to see your thread here and move it from here to there.
Please give full details of what you want to do, assumed with the Clone Stamp Tool, including a description of what you mean by "Cola gene forms".
