Cant dispell the afflicted affix

So a guildie and i cant dispell the afflicted affix today. We spammed our dispell on them at least 8 times and never worked. Anyone else have the same issue?

I’m having that problem periodically. Druid healer manually targeting afflicted and manually hitting nature’s cure button. Sometimes it works sometimes it doesn’t. Enabled targeting on healbot. Sometimes healbot sees the afflicted, and when it does I can dispel. Sometimes it doesn’t show. Random.
