Describe the bug

I'm trying to track dots on "boss5". It works for boss1-4. Putting boss5 gives me this. I would not entirely consider this a bug because It's not an issue of something giving unexpected results it seems more of a not implemented issue.

I'm trying to get another set of garrote/ruptures on the boss5 unitframe.
