[Bug] Incorrect display of dates on the time axis

### Version

### Steps to Reproduce

Hello.

After upgrading from version 5 to version 6, the customValues: [...ds] property in the xAxis configuration stopped working:

xAxis[i].axisLabel = {
...xAxis[i].axisLabel,
hideOverlap: true,
customValues: [...ds],
formatter: (value) => formatDateAxis(xAxis, value, i),
};

This property was essential for my time-type axis because, without it, the axis labels corresponding to the dates in my dataset are not displayed. For example, my data looks like this:

data = [
{ category: '2024-01-05', value1: 90, value2: 42, value3: 78, value4: 1055 },
{ category: '2024-02-07', value1: null, value2: 0, value3: 45, value4: 1189 },
{ category: '2024-03-09', value1: 64, value2: 34, value3: 58, value4: 1034 },
{ category: '2024-04-12', value1: 0, value2: 40, value3: null, value4: 1268 },
{ category: '2024-05-15', value1: 72, value2: 31, value3: 85, value4: 1076 },
{ category: '2024-06-17', value1: 15, value2: 0, value3: 85, value4: 1055 },
{ category: '2024-07-20', value1: 63, value2: null, value3: 48, value4: 1165 },
{ category: '2024-08-21', value1: 0, value2: 35, value3: 87, value4: 1145 }
]
Currently, only a single number like 1 or 17 appears on the axis, which is incorrect and misleading. How can I ensure that the exact dates from my dataset are displayed on the axis?

And if I keep this property, an error occurs:
Uncaught TypeError: Cannot read properties of undefined (reading 'level')
at leveledFormat (echarts.js?v=e1b83090:15415:24)
at TimeScale2.getFormattedLabel (echarts.js?v=e1b83090:28354:14)

### Expected Behavior

Is there any way to fix this so that I can still display the exact date values that come from my dataset on the time-type axis?
