Language bug - Custom language not working

Last night we receive a 0.68.3 version update. In this version default language is English. Since were using the chat in Hungary, a lot of people don’t understand and having trouble changing it to humgarian. Not only we have this problem, also rocket chat, so we would like to have the main registration part to have it in Hungarian, not in English pls. could you guys pls look into this problem and change it.
Thanks.

Same problem here. The default language changed to english after snap upgraded to 0.68.3. An update should not change any existing fieldvalue.
