[Resolvido] Translation portfolio

There are 2 things. Somehowe not everything is translated automatically. Sometimes it looks random. In the screenshot for example the grey text above the orange tabsis a combination of Dutch and English. In the tab Day Program. All days are still in Dutch except day 6 and 11. Most of this cycling holiday is still in Dutch while other are in English. When I go (in UK) mode to another page I'm going to a dutch page. I'm lost...
Really hope you can help. Not a clue where to search anymore...
