Incomplete IDML files may not be Studio 2019 to blame, but InDesign

Apparently, when exporting an InDesign file (.indd) to an InDesign markup file (.idml) there are some flaws, like incomplete text and misplaced text. As we know, the .idml file is the one used by Studio 2017 or 2019 for translation. These flaws are a known issue in the Adobe forums.
