Words将Word文档保存为pdf格式将丢失格式

我正在使用Aspose.Words for.NET替换文档中的某些合并字段,然后将文件保存为PDF,但是,由于转换为PDF(请参阅图片),我的格式设置变得混乱(即使是非合并字段)。代码很简单,所以我看不出我遗漏了什么。

word文档,预处理:

生成的pdf:

正如您所看到的,有些字段缩进了一点,而不是很好地对齐。

生成PDF并替换合并字段的代码是:

    public async Task<Stream> GenerateContractAsync(string requestRegistrationId)
    {
        var requestRegistration = await _requestRegistrationRepository
            .FindRequestRegistration(requestRegistrationId)
            .Include(rr => rr.Request.QualityType)
            .Include(rr => rr.User)
            .SingleOrDefaultAsync();

        var file = await _fileService
            .LoadFileAsync("Concept contract.docx");

        var user = requestRegistration.User;

        var document = new Aspose.Words.Document(file);
        document.MailMerge.Execute(
            new[]
            {
                "EmployeeName", "EmployeeDateOfBirth", "EmployeePlaceOfBirth", "EmployeeSSN", "EmployeeCity",
                "EmployeeAddress", "ContractStartDate", "EmployeeFunction", "HourlyWage", "WageDeductionApplied"
            },
            new object[]
            {
                user.FullName, $"{user.Birthday:dd-MM-yyyy}", "Oss", user.Bsn, user.City,
                $"{user.PostalCode}, {user.City}", $"{requestRegistration.Request.StartDate:dd-MM-yyyy}",
                requestRegistration.Request.QualityType.Name, $"{requestRegistration.Request.HourlyRate:C}",
                user.PayrollTaxDiscountEnabled ? "Ja" : "Nee"
            }
        );

        var mergedDocumentStream = new MemoryStream();
        document.Save(mergedDocumentStream, SaveFormat.Pdf);

        #if DEBUG
        mergedDocumentStream.Seek(0, SeekOrigin.Begin);
        await _fileService.SaveFileToDiskAsync($"{user.Id}-{DateTimeOffset.Now:g}.pdf", "", mergedDocumentStream);
        #endif

        mergedDocumentStream.Seek(0, SeekOrigin.Begin);
        return mergedDocumentStream;
    }

任何帮助都将不胜感激。
