Structure Block "Autosaving" error

I have noticed that thethe struct blocks in "save" mode are automatically saving selected areas without actually pressing the save button which is a pain in the neck esp. when I forgot to change the structure block mode from "save" to load and mistakenly typed the structure name of the area I wanted to copy, so the next time I try to copy the area I want to copy, it renders the previously "saved" area by mistake because of what I called "Autosaving" problems present in that said block. Fixing this issue will make the use of structure block in generating structures more efficient.
