vault filter exclude not working

Hi,
Everytime I deploy aem application - i18n directory inside my apps/myapp folder getting overridden in crx/de
Scenario:
added two new i18n keys in crx/de apps/myapp and did build and deploy application with following filter.xml and ui.apps pom.xml -
result: above two newly added i18n keys gone for good. overwritten by deployment.
I am thinking something wrong in my pom file (probably content-package-maven-plugin), because when I look at crx/de packagemanager deployed zip file - EDIT - Filter tab - it displays /app/myapp/i18n as excluded .
filter.xml
<?xml version="1.0" encoding="UTF-8"?>
<workspaceFilter version="1.0">
<filter root="/apps/myapp">
<exclude pattern="/apps/myapp/install" />
<exclude pattern="/apps/myapp/i18n(/.*)"/>
</filter>
</workspaceFilter>
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
