@Ann_Whitt_Wen running BP Template Pack moves the following 13 files within 6 major folders to your active WP theme: https://codex.buddypress.org/theme-development/wordpress-to-buddypress-theme/#revise-templates. Looks like member folder files are missing. Double-check via FTP/cPanel that those 13 files are there. If not, go through the BP Template Pack process again. Or, copy over the missing files/folders from BP Template Pack plugin to your active theme while maintaining folder/file structure.
