Hi Ankit,
The Calendar tries to read the actual styles, but it’s not always possible. However, there are customization events available that let you specify the styles (background color, text color, text alignment, etc.) explicitly.
To export icons and positioned texts properly, you need to define them using active areas.
I recommend using the latest release (2025.4.6770) which includes a few related fixes.
If there is any problem, please let me know.
