I've completed both of them two days ago, now I noticed in lore library tab both of them are at 0/14. Also motif pages say they can be learned even though I know them and still can craft them.
Happened to me as well. I put in a bug report and posted in the forums. It is a display issue because under achievements you still have them completed and you can craft them at any crafting station. The problem is the journal entry shows 0/14. I really hope they fix this asap.
I think someone screwed up somewhere. I think after a maintenance. Apostle and Ebonshadow are now both listed under the lore library as crafting motif 56. Apostle is 56 and Ebonshadow should be 57
