Just to clarify, the instructions I gave in my comment are there purely to help isolate the cause of the issue. I by no means meant to indicate that text must have [Basic Paragraph] style applied to it.
The intent of the steps above:
- Ensure that the [Basic Paragraph] is selected by default (and not another style, which might have a paragraph rule applied to it)
- Ensure that the [Basic Paragraph] doesn't contain a style override that applies the paragraph rule.
Once the text is imported the styling can then commence (using paragraph styles etc.).
