This issue should be resolved with patch 0.2.0. If you continue to experience this issue, please reach out to us through our support site to let us know.
Currently we offer localized text for English, French, Italian, German, and Spanish in Grounded. As we continue developing the game through this Game Preview / Early Access period, we will adding additional language support periodically so keep an eye out for patch notes for further information.
Will more languages be included in the game in the future?
