Yes, exactly, Jeff! All the "grandparent of the wife of the 6th cousin" relationships instead of "12th-great-grandparent" is completely confusing, and as you said, it makes it easy to skip over direct-line relatives in future research.
Thanks everyone for the responses--at least I know that I'm not going crazy :-)
I reported the issue. Hopefully if enough people mention it, they'll pay some attention. Fingers crossed!
Thanks again for the advice! I really appreciate it.
