Assistance with importing FM autonumbered lists appreciated

Hi. I have an issue whereby when I import an unstructured FM (v12) document into RH (v11) project, autonumbered lists in the FM files don't have correct numbering after the import.

The following describes 2 import tests I've done. (In the FM doc, lists start with a paragraph that have ListNumber1 style (<n=1>) and the remaining list items have the ListNumber+ style (<n+>).)

Import test 1:

1. I configure the import for ListNumber1 and ListNumber+ paragraphs to Convert autonumber to Multilevel list.
2. I leave the Robohelp Style mapping to the default ([Source]).
3. Perform the import.

RESULT: All items in the list in the output are numbered "1.".

Import test 2:

1. As in test 1, I configure the import for ListNumber1 and ListNumber+ paragraphs to Convert autonumber to Multilevel list.
2. For the RoboHelp Style mapping, I map ListNumber1 and ListNumber+ to BodyLevel1 (a built-in option).
   
3. Perform the import.

RESULT:None of the paragraphs in the output have any numbering at all.

Your help with this issue would be greatly appreciated.
