In my experience, this typically happens if you're using the manual layout systems, nudging and adjusting image sizes and text boxes pixel by pixel until the output is "perfect." This is brittle even in Word. You should be able to insert a section or paragraph without messing up your whole document.
Instead, use paragraph breaks, page breaks, and styles to typeset the document. Choose top/bottom wrapping of images, and keep tables simple and clean.
It usually looks better, it's easier to edit later, and it just works in whatever editor you're using - whether Office 97, Office 2017, Google Docs, or exporting to HTML.
