Hello,
In fact it appears like that because the user banners are in the same class so if you put: <xf:userbanners user="$user" tag="div" class="message-userBanner" itemprop="jobTitle" /> you will also have the mood banner.
Why ? I did this simply for all the other addons who will use the banner (because often you ban them as a user, you would also like to have them in a mood) you will also have them in mood banner, it avoids making 10 000 updates for each addon that a customer will have lol.
