[Plugin: Smart Archives Reloaded] Duplicate months

Amy:

I’m using the Smart Archives Reloaded plugin 1.8.2 with my WordPress 2.8.6. For some reason, it’s showing duplicate posts when I’m using “both” option in the settings page. Of one post, it duplicates more than 5 times of same post. How do I fix this? Is it a bug of the plugin or WP? Much appreciated.
