Heterometrus Cyaneus abdomen popping out

Hello all, this is my first post here. I recently bought my first Heterometrus Cyaneus. My only other scorpion is a death stalker. I realized that in the soft part of the abdomen between the upper and bottom scales there is like a small balloon popping out from his abdomen next to the last leg. The scorpion is very active, eats,  and seems very healthy but I don't know if this is normal or if it will be alright.

Has anyone seen this before? Is it a birth defect? Will it go away during the next molt? Should I be worried?

Thanks in advance!
