PDF Toc has inconsistent spacing betwwen numbers and titles

[Fiona]

My stylesheet includes auto-numbering for headings (level 1 to 4). All are included in the ToC. So far so good.

My problem arise when I have more than 9 headings; the title that follows the number no longer left-aligns (see attached file aaa.png).

How can I specify that the titles need to left align? If I can specify a set distance from the left margin that would work, but I can only find how to do this for the whole line (including the number) not just the title part...I could really do with something like Word's tab functionality so that I can set the tab to a particular left-margin indentation!

This seems to have been raised before (viewtopic.php?f=6&t=16842) but there were no responses.

FYI, I'm using Flare 2018r2.

Thanks. Fiona
