My site includes only pages of content, not posts. All carriage returns in my content, both in the classic page editor and when pages are displayed on the web, are converted into about 15 lines of space.
When I swap out weaver extreme for another theme this problem goes away.
WP version 5.2.3. Plugins akismet, all in one SEO, classic editor, GADWP, Google Universal Analytics, Jetpack by WP, and Weaver Xtreme Theme support.
