Blocks display at bottom of node-edit pages regardless of setting

I tried node_level_blocks for the first time this morning. When I edit a node with node level blocks assigned to the main content area, I see the blocks displayed at the bottom of the node edit form regardless of the "Display blocks on node-edit pages" setting. I tried both release and dev versions and cleared cache after changing the selection. The only way I was able to prevent this was to completely disable the module.
