There's currently a bug in the latest v13 version (1310) where the diagram.Figure field doesn't work anymore when opened in MS Word. It just shows the fixed test "diagram sequence".
Ah, yes, I noticed that one yesterday, too.
As well as the fact that the ToC sometimes uses a different numbering scheme than the heading styles- In the document I can see 1.1, 1.1.1,1.1.2, 1.2, 1.3, 1.3.1,2, etc.
The ToC renders it like 1.1, 1.1.1,1.1.2, 1.2, 1.3.1, 1.3, 1.3.1,2.1.1, 2, etc. It spontaneously seems to increase some levels and then return back to the sequence even if I am updating the ToC in Word over and over again.
Section numbering is the biggest PITA in the whole document flow as it produces inconsistent effects across the documentation toolchain most of the time and it´s been like this for a very long time now.
If you are free enough to choose the way how the documentation should look like you can start from ground with new templates and fragments.
If you want to produce documents according to a certain existing documentation standard/structure because you have to stick with safety rules et al. things are becoming quite inconsistent.
