Oh, how frustrating.
I went to the website you linked to. There’s no way to actually look INSIDE the books. And they’re apparently NOT sold at Amazon.com where you might be able to look inside.
There are so many good Catholic products these days - much like the days before everything fell apart in the 1960s - and yet many of the sellers of these products are clueless about how to market these products. So frustrating.
The Baltimore Catechism books are available from many sources - try Setonhome. They also have Eastern Catholic materials.
I agree with your point, though.
