Whenever we paste the Tracking Pixel code into an HTML content box in Content Builder the final /> is changed to > and it's causing the pixel to not validate or track. I can't be the only person having this issue since the Marketing Cloud has been pushing everyone to Content Builder to build emails. Can anyone help me figure out how to stop it from altering the code, or better yet, alter the pixel itself on Litmus to match.

Thanks,
Alvin!
