Describe the bug

From the previous version of the plugin, when adding the book to be translated, it adds some random symbols in paragraphs of the text 8 {{id_00000}} 9 randomly throughout the book that are not in the original book, and after the translation it changes the letter and the structure of the book, I add images of the original book test and after adding a translation.

Screenshots

Markers like {{id_00000}} are placeholders for retaining elements like images.

The translation behavior is unexpected because the plugin does not add any extra elements to the translation.

Could you please send me a sample for testing? You can find the email in my GitHub profile.
