A couple of options exist.

The easiest is to simply delete the agent directory for the group.
You'll loose all of your off-line content.

The next harder is to open the agent directory.  Delete the file named
.overview then rename each article file to its new number.  When
you're done, go to the summary buffer, position point on the group in
question then enter M-x gnus-agent-regenerate-group<ret>.  This will
preserve your off-line articles but you have to fetch the active
headers.
