JPG/Raw displayed separately on recent import

[#1]

On a recent import of images from my Fuji XT-4, I see that all my images are displayed as both JPG and Raw (separately). I didn't change any settings (the check box in preferences is unchecked) and previous imports did not have this issue for the last 6 years in any version of LR. 

What's up with this?

Oh, and using the most recent version of LR Classic.

There has been several posts about this recently. It seems to be caused by (Maybe a Bug In LrC) leaving older images on a card and then taking new ones and then doing an import. LrC sees the older JPGs as New files and imports them not knowing they have already been imported and possibly importing the newer JPGs at the same time.

First thing to do is ALWAYS FORMAT the card in the camera once you have done an import and before you start taking other shots.

Try that as a Test and see if the JPGs show up as separate files. I bet they don't.
