preservation Over drying

Just dryed my peppers but i can see through the skin of all the peppers is this normal? I think i over dryed them can that happen?

Unless you burned them during the drying process, the object is the removal of all the moisture so as to preserve them.
The only reason to worry about temp is for color and if you are saving seeds. IMO no matter how long or hot you dry them.,, they are always yummy!
