Now when I begin a new section and select the style for steps, instead of starting at number 1, the numbering continues from the previous list - even if it is in a different chapter. If I right-click the para and select Restart at 1, the indentation decreases for that paragraph only! The next para (step 2) is indented at the style's defined point.
Further, I've noticed that when I access the style definitions, the numbering library has nothing selected. And every time I select a number style, Word refuses to save it. That is, I save it but if I go right back into the style, there is no numbering selected.
