@alexey.noskov Please find the attached sample solution and few sample forms which are used to reproduce the issue.
sample input provided as word :
output PDF generated using aspose
Not able to upload the entire solution hence adding a code hence adding a code here
about.aspx.cs
BuildDocText :
public static void BuildDocText()
{
string fileOutputTemporary = Path.GetTempFileName();
try
{
XmlDocument xmlDoc = new XmlDocument();
string fileXmlPath = @"C:\Users\omkar.sakpal\source\repos\WebAppAspose\XMLFile1.xml";
xmlDoc.Load(fileXmlPath);
XmlDocument mergeData = new XmlDocument();
mergeData.InnerXml = xmlDoc.InnerXml;
string docType = mergeData.DocumentElement.GetAttribute("docType");
string rootPath = @"C:\Users\omkar.sakpal\Downloads\PremiumSection 2\PremiumSection\MC_PremiumSection.docx";
string outFileName = mergeData.DocumentElement.GetAttribute("PDFFile");
GenerateDoc(mergeData, rootPath);
}
catch (Exception Err)
{
throw new Exception(string.Format(CultureInfo.CurrentCulture, fileOutputTemporary), Err);
}
}
-----------GenerateDoc------------------
private static void GenerateDoc(XmlDocument mergeData, string rootPath)
{
try
{
XmlDocument xmlDoc = new XmlDocument();
XmlNodeList exportSections = mergeData.DocumentElement.SelectNodes("ExportSection");
foreach (System.Xml.XmlElement exportSection in exportSections)
{
string exportName = GetExportName(exportSection);
string duplex = GetDuplex(exportSection);
string paperBin = GetPaperBin(exportSection);
DateTime startTime = DateTime.Now;
XmlNodeList subDocs = exportSection.SelectNodes("subForm");
int subDocCount = subDocs.Count;
Aspose.Words.Document finalDocument;
foreach (System.Xml.XmlElement subDoc in subDocs)
{
string sourceFile = GetSubdocSourceFile(rootPath, subDoc);
finalDocument = AddSubDoc(sourceFile, subDoc);
}
}
}
catch (Exception ex)
{
}
finally
{
}
}
Add sub doc and merge are the two methods which uses aspose and club the forms
private static Aspose.Words.Document AddSubDoc(string sourceFile, XmlElement parent)
{

try
{
// Load the main document where others will be appended
// Load the additional documents to be appended

}
//Save the Form into PDF

The probable cause is
Once sub forms have been appended then it tries to re-align the sub form exactly below to main form where it fails and which is causing formatting and alignment issues , when the subform has large number of section than the main form
As shown in method snippet.
This method tries to readjust the section and alignment of sub form, and due to which there are formatting issues
