Install the plugin. When you open the backend error occurs.

Unable to choose a translation for "Campaign|Campaigns" with locale "ru" for value "0". Double check that this translation has the correct plural options (e.g. "There is one apple|There are %count% apples"). /home/i/***/public_html/vendor/symfony/translation/MessageSelector.php line 83

Help solve the problem. Thanks in advance for your help.
