I think that's a result of the poor combat log in FFXIV. There's a lot of stuff that isn't tracked the way you would expect. DoT damage, f.ex., never shows. The way the App parser tracks normal DoTs is that it sees the initial damage hit (and so knows the attack landed), and then just manually adds in the DoT damage based on the ratio of the initial hit compared to the DoT. I know it works that way because it will show the full damage even if you land the DoT right as a mob dies. It also shows the full 6 ticks (18 second duration) for ARC's Venomous Bite, even before you have the trait that makes it 18 seconds.

For DoTs that don't have an initial hit, the parser can't really know the damage it will do since it's never shown. I'm also not 100% sure that applying a non-hit DoT shows in the combat log.
