Valdo map doesn't give reward after completing abyss

I don't have a screenshot of the Valdo map item with conditions, but it is a Necropolis map that is supposed to reward a foil Amanamu's Gaze and the specified condition was to complete all Abysses. I cleared the entire map (including the boss) and then did the one Abyss I had found. I completed it successfully but did not receive the reward - no Singular Reliquary appeared. I have checked the entire map several times to verify there is no rare or unique monster or other Abyss somewhere.

Here is a screenshot with the report reference number, and showing the monster count is 0 (for whatever that is worth), and the opened Abyss chest.
