How change local names for weeks in highcharts gantt

I added local names in locale and change xAxis.dateTimeLabelFormats.weeks. But when I navigate to short time period, it shows Week (not Неделя as expected)

On longer time period it shows right Week name (as Неделя)

xAxis = {
    ...
    dateTimeLabelFormats: {
        hour: { list: ['%H:%M', '%H'] },
        day: { list: ['%A, %e. %B', '%a, %e. %b', '%E'] },
        week: { list: ['Неделя %W', 'Н%W', 'Н%W'] },
        month: { list: ['%B', '%b', '%o'] },
    },
}

highcharts version 9.3.3

How can I fix this bug?

Thanks for help!

This is the correct behavior that is caused by setting dateTimeLabelFormats only for one xAxis. In case of your requirements, you need to set theese options for both axis:

xAxis:[{
    dateTimeLabelFormats: {
            hour: {
                list: ['%H:%M', '%H']
            },
            day: {
                list: ['%A, %e. %B', '%a, %e. %b', '%E']
            },
            week: {
                list: ['Неделя %W', 'W%W']
            },
            month: {
                list: ['%B', '%b', '%o']
            }
        },
},{
    dateTimeLabelFormats: {
            hour: {
                list: ['%H:%M', '%H']
            },
            day: {
                list: ['%A, %e. %B', '%a, %e. %b', '%E']
            },
            week: {
                list: ['Неделя %W', 'W%W']
            },
            month: {
                list: ['%B', '%b', '%o']
            }
        },
}],
