OJS 3.3.0-3 hash tags appearing in child theme names

After upgrading to OJS 3.3.0.3, my child theme name and description are showing special characters in the beginning and at the end

##plugins.themes.mychildtheme.name##

I am using only one language in my journals (en_US).

following is in my locale.xml file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE locale SYSTEM "../../../../../lib/pkp/dtd/locale.dtd">

<locale name="en_US" full_name="U.S. English">
	<message key="plugins.themes.mychildtheme.name">Modern Cherry Red child Theme</message>
	<message key="plugins.themes.mychildtheme.description">This theme is an example of a child theme of the default theme.</message>
</locale>

Anyone can help me to get it fixed.
Thanks

Hi There
In OJS 3.3 the translation removes the XML by default. It is using po file for the translation. You should consider using po file rather than XML.

Thanks @navotera for the lead.
