I think is the PlurarSingularConverter Plugin trying to singularize the word. The thing is: when you enable that plugin (default) it expects the tables names in plural. For instances Customers become Customer, etc.
The word Status is in singular form, the plural of Status is Statuses (ref...). So as the plugin receives "Status" as the table name it doesn't find any special rule for the word, so it applies the general rule for singularization, that is remove the trailing 's'.
If your tables names are all in singular, disable the plugin, follow the link posted by Walaa. If this is an exception, you either live with renaming it each time, or you can download the SourceCode package form LLGLBen site -> Customer Area. In the source code open the Plugins project and see the Inflector.cs class. You can add an "irregular" rule for that word.
AddIrregular("status", "status");
Then compile the code and remplace the compiled dll into <LLBLGen intallation folder>\Plugins.
