The attached file TeXImport2.tex, which produces a correct PDF using TeXShop, produces an incorrect PDF when imported into SWP6 and generated by PDF Preview, see TeXImport2.pdf.

In particular:

1. the cross references in Eq. (4) do not appear in the pdf;
2. a tex command gets interpreted as output in Eq (5) in the pdf.

Are these bugs? Or am I doing something incorrectly?
