Indent when Converting to Kindle

I’m getting a weird problem where by if I compile to the Kindle format, the first word of the first section is never indented. This sometimes happens when I convert to Rtf, but is easily fixable. Any ideas?

Thanks

In the “Formatting” pane of Compile, click the “Options…” button. Is “Remove first paragraph indents” ticked?

All the best,
Keith

It was-many thanks!
