Turned Online Status Off But Still Have The Green Bubble?

Hi, Further to my message last night, I don t want certain members to know I m online because I m worried about receiving unwanted contact or them using the forum to try and immediately contact me. I unchecked the "show online status" box, but I still have my green online bubble next to my profile and posts. Thank you, Ice_Fire
