When imported in the WordsProcessing model, the current HTML doesn't respect the defined column width and all columns have identical width:

    <colgroup>
        <col span="1" style="width: 33.3302%;">
        <col span="1" style="width: 17.5658%;">
        <col span="1" style="width: 49.104%;">
    </colgroup>

Observed result:

Expected result:

Workaround: use the width property as follows:

    <colgroup>
        <col span="1" width="33.3302%">
        <col span="1" width="17.5658%">
        <col span="1" width="49.104%">
    </colgroup>

When importing and merging documents the fonts are extracted directly from the files and can duplicate if the files contain the same fonts.

 An incorrect file is produced when merging a stream more than 40 times.

Workaround: A possible workaround could be to merge up to 40 times in one file, then continue merging in a new one, and finally merge the newly generated documents.

This is the code for import/export which result is illustrated below:

            string inputFilePath = "test1.doc";
            Telerik.Windows.Documents.Flow.Model.RadFlowDocument document;
            Telerik.Windows.Documents.Flow.FormatProviders.Doc.DocFormatProvider doc_provider = new Telerik.Windows.Documents.Flow.FormatProviders.Doc.DocFormatProvider();
            using (Stream input = File.OpenRead(inputFilePath))
            {
                document = doc_provider.Import(input, TimeSpan.FromSeconds(10));
            }

            Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider docx_provider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
            string outputFilePath = "Exported.docx";
            using (Stream output = File.OpenWrite(outputFilePath))
            { 
                docx_provider.Export(document, output, TimeSpan.FromSeconds(10));
            }

            Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });

Opening a file where there is a format string with modificator [Color11] causes an ArgumentException "Invalid modificator" This prevents the file from opening.
