A TOC field regenerates its rows from the styles named `toc 1`…`toc 9`, and its cached rows are skipped on import — so those styles were never seen and the index fell back to the editor's 0.5cm per level, dropping the file's space-after with it. Measured on a 60-row index: a 5.1mm row pitch against LibreOffice's 6.9mm. They now land as Contents 1…10, and the DOCX export writes the rows back under them instead of the fallback indent.
