Hans,

Thanks for replying, Actually I realise the problem is with column break (was a bit late when I wrote my message, sorry for this).
I prepared a small example + output I get.

I am not saying the output is necessarly bad, but I’d like to know how to avoid the paragraph being broken and the 4 empty lines in the first column (at least in the example), or know what I am doing wrong. It looks like there is some setting “attaching” the last 2 lines of paragraph to the next section heading.

Thanks

Best regards

Joseph

you need to make a (minimal) example that shows the issue
