Unless you specify a text indent for the first line (in Word that's under the paragraph formatting/special, and in html it's text-indent:), then the Kindle will auto indent the first line of each paragraph, which may cause unexpected results.
It's best to set indents yourself to avoid everything messing up,
After hours of aggravation I found the problem! Font size, I was working with a font of 12 after I brought it down to 10 everything fell into place. If you are having the same problem I hope this helps.
That really sounds like you've manually entered a line break at the end of each line in Word, rather than letting the text flow naturally within a paragraph. If that is the case you will want to correct that issue before publishing.
While decreasing the font size may correct this issue for the default text size, as soon as a reader selects a larger font size (or opens your book on a device other than an eInk Kindle, such as Kindle Fire or their mobile phone) it will blow up again and they'll have a very difficult time in the reading.
Also, keep in mind that "12pt" in Word results in text that is the "standard" size for Kindle books. By deviating from that standard you are inviting readers to change the text size.
If your paragraphs are formatted properly the text will not indent erratically. If they are not, you will want to fix the core issue rather than publishing a book that contains a "bandage" that only works under specific reading conditions.
You can determine if this is the issue with your book by enabling the "show formatting" option, which is accessible in Word (and many other word processors) by using the toolbar button featuring a pilcrow (¶). If there is a paragraph mark (¶) or line break (hooked arrow pointing left, as probably exists on your Enter key) at the end of each line you will need to remove those, resave your file, and then upload the revised copy to KDP.
