That's not necessarily inconsistent. In order to upgrade anything in the Laboratory, you have to unlock it first. The Lightning Spell upgrade doesn't appear in the Laboratory until the Spell Factory is built, the Minion upgrade doesn't appear until the Dark Barracks is built, etc. The upgrade may be available at Laboratory level 3, but the spell hasn't been unlocked yet so it doesn't appear.

Just because you can have a level 5 Laboratory at TH7 doesn't mean you have to have a level 5 Laboratory at TH7. It's possible, though unlikely, that a player may have upgraded their Town Hall and Spell Factory without upgrading their Laboratory. Does the upgrade actually appear in that case? The assumption is yes it does, but currently we have no evidence either way. We are attempting to verify it, but if you already have screenshots supporting or refuting it we would love to see them.
