New line appears with a leading '15-'
-
In the past few days, whenever I press the [Return] key twice in order to get a blank line and a new paragraph, the last [Return] creates a new line with a leading ‘15-’ text. I’m sure I haven’t chosen any option causing this and found no way to prevent Notepad++ from continuing doing so.
What has gone wrong and how can I switch off this behavior?
