Problems with the visualization of the life bar in the dungeons (Elvui)

[Brianzz7]

Hello, 2 days ago I have a problem with the addon ElVui which is, I can not see the life bar of the group or band inside the dungeons, I am still trying to find some solution to the problem they recommended to me to consult in the forum of the server to ask the community if they experienced the same problem and how they could solve it.
Disable addons, change them for others, all downloaded by the server page and even then I still have the same problem, some solution or tutorial which can give me to solve this error?
Try download the same addon in other websites, reinstall them, search for configurations, etc. But I can not find the problem, the strangest thing is that the life bar does not appear to my band or band partner, only that, it works with adds but it's very rare
