That's not a bug, that's a feature!

Life, Entropy, Spirit=Necromancy or Alteration (for some spells in older editions)
Forces=Evocation
Mind=Enchantment
Prime=[metamagic] or Abjuration
Matter=Transmutation
low-level spheres=Divination ('sense' is often the first level)
Time doesn't fit all that well.
But overall it fits better than one might expect.
If I had more time I'd produce 1e stats for Voormas, Grand Harvester of Souls. Or, heck, Caine.
In the system that I'm building, the magic skills are a bit more complex due to each having 3 specializations. Each character ends up with a lot of skills, and then the game gets incredibly simple from there. Basically, each skill and specialization does a lot of work but skills don't have their own rules generally. Anyway, as follows;
Aeromancy (Gale, Whisper, Wind-Walk) - air magic, moving air, creating sound, using air to move yourself or another creature.
Alchemy (Preparations, Sigils, Transmutation) - making stuff, symbolic magic, changing elements
Beguile (Charm, Empathy, Glamours) - Fairly self-explanatory, Glamours are illusions and other mental tricks.
Divination (Augury, Sight, Psychometry) - Reading signs, seeing through glamours and/or seeing truth, and seeing through objects and places, into their past present and future.
Echomancy (Echokenisis, Echolocation, Resonance) - manipulation of sound and vibration, navigating by sound,
Electromancy (Conductivity, Lightning, Signal) - manipulation of electricity, including messing with electronics
Enchantment (Meta-Magic, Imbuing, Place Magic) - Manipulation of existing magic, enchanting items, creating magical effects in a place or enchanting a location
Geomancy (Earthsense, Stone-skin, Inertia) - nav by vibration, defensive stuff, and moving stuff around, including teleportation
Hex (Bind, Curse, Invoke) - deeply personal magic, invoke is using a name as leverage against a creature
Hydromancy (Biomancy, Hydrokenisis, Cryokenisis) - manipulating water, including healing creatures and making things of ice
Pyromancy (Combustion, Convection, Luminance) - Manipulation of fire, heat, and light
Sacramancy (Bless, Cleanse, Rebuke) - channeling of the divine, or sacred articles, etc
Sombramancy (Shadow-Walk, Sombrakenisis, Vitiate) - manipulation of shadows, internal and external, including effective teleportation
Shamanism (Commune, Restoration, Spirit-Walk) - dealing with spirits and the spirit world
