AdvStringGrid & AdvGridExcelImport

Hi,
when I load the grid with AdvGridExcelImport1-> Import () the grid becomes white while before with AdvGridExcelIO the grid remained the color of the application theme (dark)
What can I do?

Grid 8.6.14.0
ExcelImport 3.1
Thanks!

Did you set AdvGridExcelImport.ImportOptions.CellFormatting = true?

Ok thanks with CellFormatting = false it works
