This is a glitch in the 5.1 release of YouAtNotes Workflow and will be resolved in the next release.
The reason is that in the "postOpen" event of the database script the language is not loaded, so all texts are falling back to their default language (which is german in the moment).
To fix it by yourself, do the following:
- edit the database script in Domino Designer
- add "use .yn.lscript.universalTranslator" to the "use" section
- add "call loadLanguage()" in the postOpen event
- close Domino Designer, close the app in the Notes client, re-open the app -> now the texts should be english.
