Form Fields is lost after ODT to DOCX Translation using Java

When converting from ODT to DOCX the form fields are not preserved.
The tick box form field is preserved, however the size of the field has not been preserved.

Using - aspose-words-20.8.0-jdk17.jar

Using this code:
com.aspose.words.Document doc = new com.aspose.words.Document(inputPath);
doc.save(outputPath, com.aspose.words.SaveFormat.DOCX);

Please note that Aspose.Words mimics the behavior of MS Word. If you open and save the ODT to DOCX using MS Word, you will not get the checkboxes. So, it is not an issue in Aspose.Words.
