Raise Spectre with new corpses another bug

So, here's a new bug (or the same one) I've got just now.

My max spectre count is 3, and all actions are made in hideout
Here's the order of my actions and what happened:

1. I had summoned 2 Flame sentinels and 1 Imperfect Shadow Construct
2. I unsocketed my Raise Spectre gem, all 3 spectres died and spanwed it's corpses.
3. I raised 1 Imperfect Shadow Construct and 1 Flame sentinel
4. I used new vendor corpse: "Perfect Spirit of Fortune", it spawned on the ground
5. I used Raise Spectre on this exact corpse, making sure it's the right one (Perfect Spirit of Fortune)
6. Another Imperfect Shadow Construct was raised as my spectre instead of Perfect Spirit of Fortune
7. Just to make sure I am sane, I unsocketed my Raise Spectre gem to check corpse names. It turned out to be 2 corpses of Imperfect Shadow Construct and 1 corpse of Flame Sentinel

WAIDW?

My another previous reported bug regarding to new spectres. It might be the same issue, but I'm not sure.
