The view in question is:

The language of the system in this picture is Portuguese but the elements in the dashboard section (where it shows the RFQ purchase statistics) is still in English (US) - the default.

The file that show the bit corresponding to the dashboard is given by a static view in 

./addons/purchase/static/src/views/purchase_dashboard.xml

An example of the code from the file above that results in this is in lines 8, 9 and 10.

The contents relating to this bit of the pt.po file are as:

#. module: purchase
#. odoo-javascript
#: code:addons/purchase/static/src/views/purchase_dashboard.xml:0
#, python-format
msgid "All RFQs"
msgstr "Todos os RFQ"

After the changes to the .po file there is always an updating of the language with the replacement of all translations and the corresponding reload of the web browser page. The fact that all other strings appear as translated in the .po file goes to show that the correct procedure was taken to enable and update the pertinent languages.

So the question here is. What am I doing or is there some bug or design issue that needs to be changed somewhere?

This is as far as my knowledge of odoo innards goes.

Thanks for any help,
