I am performing a bulk edit, and specifying, on step 3, which fields I want to edit. For example, I was changing the security level to a particular value in the dropdown. Then I pressed "Next" to get to step 4. The very nice reminder that email notifications would be sent led me to click on the link for step 3, as is suggested if you want to edit your selections. But when I did so, it lost/forgot my previous selection, setting Security Level to "None". Luckily I caught it before confirming, but it should not have forgotten it since I am using the suggested method to make edits.
