That’s definitely odd because it’s showing damage for me. Can I get a link to the character this is happening on?
@Eve My bad, I just noticed no spells have damage in the spellbook where this screenshot is coming from. 
Sorry.
No worries! That’s an interesting issue and I’m not sure where it could be coming from. My normal solution would be to see if it happens again if you recreate the character, if you give that a shot please let me know if the problem does come back because that’s something I’d like to get over to our dev team.
