Estoy usando titlesec para eliminar el espacio entre la sección y el texto, \titlespacing{\section}{0pt}{0em}{0pt}{}pero esto no funciona entre el final del párrafo y la sección, los valores negativos simplemente se ignoran \titlespacing{\section}{0pt}{-1em}{0pt}{}.
\documentclass[12pt, a4paper]{extreport}
\usepackage[margin=2cm, top=2cm, right=1.4cm, bottom=2cm, left=2.8cm]{geometry}

\linespread{1.5}
