Stellar Amulet's in-game drop/required level does not match metadata, causes filter problems

In-game, Stellar Amulet has a required level of 24, and the lowest item level (=drop level?) available on trade is also 24.

The corresponding implicit modifier (Metadata/Items/Amulets/FourAmulet8) has a level of 31, which after applying TRUNC(31*0.8) should equal 24.

However, the baseitemtypes.datc64 seems to indicate it corresponds to a drop/required level of 25, rounding 24.8 incorrectly?

Additionally, Loot Filters can only show Stellar Amulet if it is specified DropLevel == 25, not 24.

There seems to be a discrepancy with items violating the assumed minimum level. It would be great if this could be looked at to ensure there's not something strange going on in how the metadata is being translated into game stats.
