Anti-Splog has two entries on Plugins page

I upgraded my Anti-Splog installation (1.0.5) to use the plugins folder and ran into an issue.

First I removed my Anti-Splog installation:

rm wp-content/blog-suspended.php

rm -rf wp-content/mu-plugins/anti-splog*

Next I re-installed according to the instructions, putting back blog-suspended.php (guess I didn’t need to delete it) and moving anti-splog* to wp-content/plugins

When I view the Plugins page, I see 2 entries for Anti-Splog.

Did I do something wrong, or is this normal?
