Formatted text imported in a rich text field, stays flat untill I open and save the entry

Hi,

Very nice plugin you have. Thanks for that!
I got a problem with importing pre-formatted text form a different CMS (only headings, links and paragraphs and maybe often UL/OL.
All the content is there, but you see no paragraphs in the frontend, until you open and save the entry in the CP.
How can I do this for about 2400 entries without having to open and save them all per entry?

Thanks in advance!
