Note

This is not only affecting the Russian language, but it is affecting the German (Switzerland) language as well.

Workaround

• Change the default language to English (US), create the IT Service Desk project then change the default language back to Russian
• If the instance's language was Russian when Service Desk was started, then the Service Desk fields were created using Russian. For this case, changing the language to English is not enough. You should do the following:
  • On custom field's page, look for Изменить тип
  • Click on the cog icon next to the field > select Configure
  • On the options section, add Normal
  • Change the instance's language to English and then you should be able to create projects.

Please note that when you change the language to English and then create a Service Desk project, some configuration for the project would be saved in English
