Blessed Remission halts the time Healing Curse duration however the affects of Healing Curse are still applied. So Blessed Remission actually makes Healing Curse worse by making it last longer.

Also as a second bug, when you do Angel's Wing with a sword, you'll sometimes get the message about leaving an open wound, but there is no bleed damage. Figure you shouldn't get the message if there is no bleed. Now sometimes it works totally fine.
