2014 LSC DDR?

These shield cents are very confusing to me lol. I see on some of these coins what appears to be a doubling of the lower left side of the shield. I do not think it is a part of the design(I could be wrong) because not every coin appears to have an "Extra shield Rim." Here are some pictures. Purple indicates the possible doubled part. The blue arrows point out the two distinct separate lines or shield rims. The third picture is from a different angle which clearly shows the area in question is raised. I appreciate your help.
