Dashboard Studio templates contain strings for all supported languages. These include English, French, German, Spanish, Dutch, Portuguese (European), Portuguese (Brazilian), Japanese, Simplified Chinese, Traditional Chinese, and Korean. As a result, the dashboard may be slightly larger.
The Language Properties frame enables users to remove unnecessary languages from templates, editable source master (ESM) documents, or runtime dashboards. The frame is available in Release 8.5 and later templates.
To use the Language Properties frame to remove languages:
In Interactive Reporting Studio, navigate to Language Properties.
To access the configuration frame, use Sections or the Configuration drop-down list found in Dashboard Studio.
Move selected languages between Available Languages and Languages to Remove by clicking

Click OK (The selected languages are removed from the ESM)
Click Apply at Runtime to remove languages when the document is converted into a runtime release.
In this case, only the runtime document is affected and all languages are still available in the template or ESM.
Note:
English is the default language for dashboards and is not available for deletion.
