Scheming Schema(ta!)

I just completed a voyage to sector 5 and received the following message:

The Armada exploratory voyage finalized.
You obtain 2 toy box schemata.

However the tooltip for the item, the name that appears when linked and the name on the item in my bag is:

Toy Box Schema.

The voidsent are scheming again to confuse the poor souls of Eorzea with mislabelled items! Deliver us from this evil plot of befuddlement!

I believe "schemata" is the plural form of "schema," so this should be correct.
