Not able to defeat Class A Temporal Anomaly

On PS5, don't know if this makes a difference or not...

I don't know if this is just a me thing or not, but if I beat the new Temporal Anomaly that pops up randomly in the DSEs, I will get the drops once. If I do another DSE with the Class A box in my inventory, I cannot beat the next Temporal Anomaly. It will just fade away.

I have beaten the anomaly maybe 6 times, but every time I did not have a box in my inventory. Any time I had a box, I can get the anomaly to 1% health then it fades away without dropping anything.

Has anyone else seen this behavior? Can anyone else confirm?
