According to your plugin list, MapChooser (the default SourceMod one) is running, and MapChooser Extended isn't.

There are also mixed versions of the Allied Modders plugins for SourceMod... they should all be the same versions, likely 1.3.9-dev if that's the SourceMod version you're running (personally, I stick with 1.3.8 which is the current stable version).

Having said that, having both MapChooser and MapChooser Extended running at the same time could cause potential problems and is an issue I should address in the next version.
