When using an uploaded image for a video thumbnail, the image's color becomes distorted once inserted. It looks as if the image's color becomes negative. I have tried deleting the block and retrying. It does not work. I have tried starting the email over. It does not work. I have tried to see if the problem is whether or not it is specific to Vimeo or YouTube, etc. It is not. I have tried sending the email to see if it only looks that way in the edit mode. That is not the problem. In fact, when it prints, the problem is worse. This is not the case when I use the video's original video thumbnail. The problem seems to disappear. What is the issue?
