Linked FrameMaker to RH, Numbered Lists w/No Space after Autonumber

My FrameMaker book is linked to RoboHelp. Initially in the RoboHelp conversion settings, I set the FM numbered list styles to "Convert Autonumber to HTML List" and mapped them to BodyLevel1 and BodyLevel2. That worked fine for the 1st level steps (1, 2,3, ...), but the indentation of the substeps (a, b, c, ...) was weird. The substep text was indented correctly, but the a, b, c autonumbers were aligned directly under the 1, 2, 3 step numbers, leaving a big gap between the autonumber and the text.

Then I set the FM styles to "Convert Autonumber to Text". That let me control the indentation of both levels of autonumbers, but there was no space between the autonumber and its text. Although I changed the indentation parameters in all sorts of ways, I could not create a gap between the autonumber and its text.

Anyone have any idea about what I'm doing wrong or something different I could try?
