Trying to print an ammended return on TT2021 desktop. When checking, I see Sch K-1 has missing pages. Tried to print separately, it doesn't print them.

When I look at the form in the software, the pages are there, in the Forms option.  But cannot print from there. The form has 9 pages, and only prints 1-2,5-9, skipping 3-4.
When I checked my original return PDF that was e-filed, it also is missing those pages
