Looks to be an issue with DamageIndicators rather than Ancient Warfare. Please report the issue to that mods' author. More precisely, there is nothing I can even to do look into the issue, as DamageIndicators is closed-source (at least I cannot find a source-listing on their mod-page) -- so a fix will need to come from that mods' author.
