Describe the bug
When creating a new event with an unsupported language, the system allows the event to be created and added to the event list.

Steps to Reproduce

• Create a new event and Select a language
• Enter an event name in a language which doesn't match the selected language
• Set the default language to an unsupported language and submit the event

Expected behavior

• The event creation form should validate the language code against supported languages
• Event should not be created or added to the event list if the language code is invalid
