Open the attached document.
Numbering should increase like this: 1, 1.1, 2, 2.1, 2.2.
Instead it's: 1, 1.1, 2, 1.2, 1.3.
Observed using LO 22.214.171.124.alpha0+ (2018-09-22, 8b1501d80dc9d3f42c351c6e026fa737e116cae5) & 3.3.0 / Windows 7.

Messy DOC with Heading3 is 2nd level numbering. So I set to Low.
But repro with today's 6.4+. No repro if DOC saved in MSO as DOCX.
