I don't know which Fansub group the episodes you have are from, so i can only advice you to ask that in the group's IRC channel...

i like the series, though i feel that ep 12 & 14 were complete unnesscerry filler, and they come at the worst time ("hey! instead of showing you Joushua and Aion, we'll torture you with X-mas and demons having fever!"), but sinse it's going to be a 26 episode (probably) series, it's ok for them to stick in a bit of filler crap after the exposure and before the final part...
