"exportTitles" does'nt export the value of the title

[oijkn]

Hi,

When I use the following example from amCharts Tutorial and then add the parameter "exportTitles": true.

After exporting charts to XLSX, the value of the title doesn't appear in the name of the columns.

As you can see in the screenshot above, the title is missing in red marks.

Is it possible to explain to me how I can do to display the value of the title in the columns, please ?
Concerning violet marks, is it possible to delete the prefix or rename it ?

Thank you in advance for your support and help.

BR.
