Inconsistency with Boolean multiplication

[BigBeachBananas]

Book1
	F	G	H	I	J
21	TRUE	TRUE	TRUE	0	1
Sheet1

Cell Formulas
Range	Formula
I21	I21	=PRODUCT(F21,G21,H21)
J21	J21	=F21*G21*H21

Why do I get the wrong result in column I?

Note: If an argument is an array or reference, only numbers in the array or reference are multiplied. Empty cells, logical values, and text in the array or reference are ignored.
