Armor of Vulnerability is missing links for each armor type.

Half Plate is duplicated and Plate is missing.

Dragon Slayer 
Greatsword, Longsword, Rapier, Scimitar, Shortsword still point to legacy versions of the items.

This isn't so much a bug as just D&D Beyond deciding not to create duplicate 5.5e versions of 5e magic items that didn't have any changes in the new rules.

The only change with the Dragon Slayer in 5.5e is which weapons it applies to — the old one could only be swords, while the new one can be any weapon at all. They added 5.5e versions for the newly available non-sword weapons, but just kept the existing 5e versions of the sword weapons because their behavior is identical in 5.5e.

Now, I would say that means the 5e ones shouldn't be marked "Legacy", but they don't seem interested in changing that.

Armor of Resistance is missing links for each armor type.

The Wand of Orcus doesn't appear as a weapon in the "actions" section of the sheet. It's just... not there. I don't remember the 2014 version having this problem.

It looks like the 5.5e Wand of Orcus is classified as a Wand in D&D Beyond, which is why it's not showing up with a weapon action. The 5e one is classified as a Weapon.

Both versions of the DMG have its category listed as Wand, so the 5.5e one is technically correct in D&D Beyond. But since DDB needs it to be a Weapon for it to actually work properly, they should probably both be Weapons in DDB.
