With Sitecore Data Exchange Framework installed on Sitecore XP instance, creating a new tenant in a certain content language might result in the creation of the tenant in a different content language.
For example, creating a tenant in Chinese will create a tenant in English.
The issue affects Data Exchange Framework 6.0 and earlier versions.
To resolve the issue, import language translation that can be found in the Data Exchange Framework zip-package at \files\temp\Data Exchange Framework to both core and master database. To that end, perform the following steps after the Data Exchange Framework package installation:
Note: For any connector like Dynamics CRM Connect, Salesforce Connect, Sitecore Connect for Salesforce Marketing Cloud, it is needed to import the language translation separately, using the above steps. Language translation can be found in the Connector zip package, for example, in \package\files\temp\Dynamics Connector.
