I'm trying to show major ticks on the x-axis while using the type: "timeseries" option, but they are not showing.

My x-axis options:

xAxis: {
          bounds: "ticks",
          grid: {
            display: false,
          },
          type: "time",
          time: {
            unit: "hour",
            stepSize: 3,
            displayFormats: {
              day: "d. MMM",
              hour: "HH:mm",
            },
            tooltipFormat: "EEEE, MMM dd, HH:mm:ss",
          },
          adapters: {
            date: {
              locale: pl,
            },
          },
          ticks: {
            maxTicksLimit: 7.1,
            // source: "labels",
            maxRotation: 0,
            major: {
              enabled: true,
            }
          },
        }

Without ticks.source: "labels" major ticks are showed. How could I make it work with the source: "labels" option
