Can't read the correct content type for .xlsx files (application/vnd.openxmlformats-officedocument.spreadsheetml.sheet)

[ahmed-a-e2006]

When I try to get the content type for the uploaded file test.xlsx, I got wrong content

ContentInfoUtil contentInfoUtil = new ContentInfoUtil();
ContentInfo contentInfo = contentInfoUtil.findMatch("D:/test.xlsx");
System.out.println(contentInfo.getMimeType());
System.out.println(contentInfo.getContentType());

I got this output

application/vnd.openxmlformats-officedocument
MICROSOFT_OFFICE

and it should be

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
MICROSOFT_EXCEL_XML

I attached the excel file that has this problem

Note: I tested it on version 1.16 and 1.17

test.xlsx
