[Coldbox 5.3.x ] i18n issue

I’m developing an application using the cbi18n module.
In my Coldbox.cfc DEV-Environment I have the setting

wirebox = {
singletonReload = true
}

to disable model caching in development.

Unfortunately, I get this error:
Type: i18N.DefaultSettingsInvalidException
Messages: The LocaleStorage setting cannot be found. Please make sure you create the i18n elements.

If I remove the “singletonReload” from ColdBox setting, everything works fine.

Any ideas? The setting “LocaleStorage” is set to “cookie” (also in Colbox.cfc; i18n.LocalStorage=‘cookie’)
