It appears as if a portion of the Celestials section was dropped down into the Constructs section, meaning Celestials have 2 headings and Constructs don't have one, shown below:
Celestials are creatures native to the Upper Planes. Many of them are the servants of deities, employed as messengers or agents in the mortal realm and throughout the planes. Celestials are good by nature, so the exceptional celestial who strays from a good alignment is a horrifying rarity.
Celestials include angels, couatls, and pegasi. Constructs are made, not born. Some are programmed by their creators to follow a simple set of instructions, while others are imbued with sentience and capable of independent thought. Golems are the iconic constructs. Many creatures native to the outer plane of Mechanus, such as modrons, are constructs shaped from the raw material of the plane by the will of more powerful creatures.
