Error in Schweser, the Intenational Parity Relationship chart

In the chart International Parity relationship Combined, page 249, Los 13f, the relation between Exchange rate expectation and Inflation rate differential is : REAL purchase power parity.

The right relation is EX-ANTE purchase power parity (Curriculum book 1 page 533).

Could you confirm whether I am right and there is really an error in Schweser?

I hope you all hadn’t relied solely on Schweser, if not, it’s sure you had trouble.
