DOCX files exported with DocxFormatProvider contain a BOM in every exported XML file. Some programs fail to load those DOCX files.
Please remove the BOM, or add a toggle in DocxExportSettings.
Updating a Table of Contents field with a custom TOC Style does not respect it.
As a workaround modify the style after the TOC fields are updated.
With the current implementation of the RadFlowDocumentEditor`s CharacterFormatting.FontWeight.LocalValue accepts only FontWeights.Bold and FontWeights.Normal and throws an exception when setting different weights (ex. Black, Thin, etc.).
When mailmerging a document, with nested mail merge group which starts inside a table and ends outside the table, a NullReferenceException is thrown: "System.NullReferenceException: 'Object reference not set to an instance of an object.' firstParagraphInTemplate was null."
Workaround: move the group end (EndGroup, TableEnd, RangeEnd, or GroupEnd) merge field inside the table where the group starts.
List's top and bottom margins are not correctly exported.
Workaround: Apply TelerikNormal style to the 'ol' element.
