Hi Team,

If we change the default language of an account to Russian, the system field translation of Summary is presented as Pезюме, which is incorrect. It should be Резюме instead.

Though both words seem identical, the initial letter in Jira's Summary field translation is the English alphabet 'P'. You can distinguish this by using the search function (ctrl/cmd+ F) and typing in 'P', which will highlight the discrepancy.

The following video recording provides additional clarification on this issue.

Suggestion- 

Please change the Russian language translation for the Summary field to Pезюме from Резюме
