1. To remove the green double-strikethrough or double-underline, simply select the text and click on the "Strikethrough" or "Underline" button again to turn off the formatting.
2. If you want to remove all formatting from the text, you can select the text and then click on the "Clear Formatting" button in the "Font" section of the "Home" tab.

If you're seeing these formatting options in a document that you didn't create, it's possible that someone else applied the formatting intentionally. However, it's also possible that the formatting was applied accidentally or as a result of a compatibility issue between different versions of Word.

If you're still having trouble with the formatting, you can try copying and pasting the text into a new document to see if that resolves the issue. If not, you may need to manually remove the formatting by selecting the text and using the "Clear Formatting" button.

I hope this helps! Let me know if you have any other questions.
