Did you try using field behavior to make these fields inaccessible when in browse mode? Shouldn't be needed for fields set up as buttons, but since you keep getting that pop up...
You might also click on Report an Issue and report this as a possible bug.
Yep, already tried that. No dice.
Thank you for your post.
Our Testing department reported they are able to replicate the issue, and the information has been sent to Development for review. I will keep you posted as more information becomes available.
