missing conjurations

[midnight vine]

I'm missing 9 conjurations all in the exploration section but I don't know how to find them exactly bc I am having an issue where my maps shows a chest but I have already opened it

[whole thicket]

In summary, there are 12 collection chests in total within the fantastic beast nurseries (there are 3 chests per room, 4 rooms in total). When this bug happens to you, one of those 12 chests will be repeated, you can open it a second time and it will give you a different reward, so there will be 13 rewards in total. This is how you can get the reward from the collection chest that you couldn't open.

@midnight vine I got the same bug about the chest that does not give the reward, if you have already done the steps that I gave you and you still need them, don't forget to visit all the butterflies
