importing text into Indesign - its backwards

As @John Mensinger said, you're bringing in Google Doc's manual formatting code along with the text. You need to strip it out, which is what "Clear Overrides" does.

But our studio has found that "clear overrides" doesn't always scrub the text clean enough and leaves some strange hidden coding in the text that causes problems for our automated publishing workflows and exports to accessible tagged PDF.

So we prefer to do a thorough scrubbing of the crud so that it doesn't cause any problems during production. Especially important with Google Docs, which leaves a lot of residual code crud in the file.

If you use File / Place / Show Import Options to bring the content into your layout, you can strip out the formatting during the place procedure. Set the import options to these settings, which strips out all formatting (both manual overrides and styles) from the incoming file:

1. In Google Docs, save the file as Word.docx file format.
   
2. In InDesign, use File / Place / Show Import Options which gives you control as to how much formatting (if any at all) is imported from Word.docx files.
3. Select these options to strip the document clean:
   
   Check "Remove Styles and Formatting from Text and Tables."
   UNcheck "Preserve Local Overrides."
4. If the original Google Doc used formatting styles which were transferred into the Word.docx version, those styles can be "mapped" to your InDesign styles with these import settings:
   
5. You can save either set of settings as a present to use with future documents.
