Powering down and back up has no effect. If it would, it would have fixed it when I cycled the power on both the Fire and the Computer.
One thing I just noticed in device details under 'USB controlled by', 'This device' is checked. when I try to go to 'Connected device' it says switching for 20 seconds, then changes to Couldn't switch. But it did change the 'Use USB for' from 'No data transfer' to 'File transfer' Didn't do anything. Changed it from 'No data transfer to Midi and a pop up window says KFNOW, or something like, that loaded. Then clicked 'PTP' and the same popup and KFNOW came up. Back to and clicked File transfer and a pop up came on the Calibre screen that said something about the Fire HD 8 and asked if I wanted Calibre to control this device. I clicked yes and the transfer buttons on Calibre showed up. And it just loaded book 11 from my book series. So this is where all of this has to take place. And it wasn't one time clicking things to get it. And partially proves my theory that Amazon did something to make it seem impossible to get it to work like the Fire 7s worked out of the box with no hoops to run through. One more thing.....It seems really weird to me that someone who is as computer illiterate as I am found the issue.

After playing with it a little more, I find if I disconnect the USB cable, I have to go back and mess with the above to get it to load another book. Also, in it still doesn't show the folders in File Explorer. Not sure what's up with that.
