See if this page provides any solution. Peter's page is still under construction with regards to multi-level lists but it sounds like you may not be using them. There is also some useful info regarding potential issues with projects upgraded from before RoboHelp 8 is this is the case with you.

Sorry, which page?
The RoboColumn? It's interesting because I can't see anything obvious in the css that would cause this either but it's a bit annoying because it's making the presentation of my helpfile look really rubbish!
I have the exact same problem. I suspect that it is a problem with my custom .css file, as I tried it with the default style sheet and don't get the indentation problem. I am on a later version (8) than my colleague that I inherited the .css from, so maybe there is some compatibility issue. I would be interested to hear if anyone has had a similar problem and were able to resolve it. This is the style for the numbered list (with left margin at 0cm.)
Normal + font-size: 10pt; font-family: Arial, sans-serif; color: #003366; line-height: 120%; list-style: decimal; margin-top: 10pt; margin-bottom: 10pt; margin-left: 0cm;
This looks like the infamous RH8 list problem. Please follow the link Colum provided and post back if you need more help.
Thanks for providing the link below:
Fixed using the Tools > Gen > Convert to HTML option, as described in the PDF.
