Sudden black line over oder under text in Office Writer: how to get rid of it?

Hello,
How can I get rid of a black line which suddenly appears in a text in Office Writer??
I tried to delete it with Format-Paragraph-Frame but impossible to delete this black line.
How could I achieve that successfully??
Many thanks in advance for your help!!
