See bottom 3 items in the screenshot:
That’s because Dutch language server.yml has the 65% translated.
Please join the team, and help them to translate.

That’s incorrect. You cannot translate the Advertising plugin in Transifex.
You need to locate the repository in Github and create new files server.nl.yml and client.nl.yml. You can copy the English files to clipboard and paste the content into empty files. Then you change the first line from en: to nl: and translate everything. Once you are done, you submit pull request. You might have to sign the Contributor License Agreement also if you haven’t done so already. Here is the repository for this particular case: https://github.com/discourse/discourse-adplugin/tree/master/config/locales
I agree that the Dutch locale needs contribution so getting familiar with Transifex is a great idea anyway! 
Edit. The advertising plugin is now available in Transifex. See @neil’s post a few posts below.

Thx! BTW: It’s for the hosted/SaaS version.
Or., create that files as @rizka said, and send the pull request for the main repo, so discourse’s team can approve it and when your hosted version upgrade from main repo (from plugin) then catch up the files, and put new translations in “dutch”.
Of course when you create that files, you must translate all the sentences.
I’ll add the adplugin files to Transifex so you can translate them easily.
