It's a bug in older releases of WOLips. Please refer to the welcome.xml
to get rid of it. Choose Help->Welcome->WOLips about from the menu.
To be more detailed. WOLips adds your EOModel twice to the PB.project
and that causes your EOModel related problems.

The default build.xml has different targets. To install your frameworks
once:
Open the context menu for the build.xml and choose "Run Ant...".
In the dialog select install instead of build.
This will install your framework under localroot.
To set the install to localroot/foo:
Instead of:
<!-- basic initializations -->
<target name="init.install">
<tstamp/>
<property name="dest.dir" value="${install.dir}"/>
</target>
this:
<!-- basic initializations -->
<target name="init.install">
<tstamp/>
<property name="dest.dir" value="${install.dir}/etc"/>
</target>

Most of us prefer EOGenerator to create the src files for a EOModel.
EOGenerator has much more features and less bugs then WOGenerator.
Search the list for usage examples
