2 catalog mistake.

A little history:

So somehow when I very first started importing photos to my catalog, my first import went great then my next 3 were a mess/lost and I received help on here with the advice to find the parent folder and sync. That worked and I found those missing 3 imports that contained 41 images and all has been great. This is all seen in my very first posts on here around September 22.

I have my LRC catalog and all images on my external SSD and things have been working great. Just now I decided to look on my MacBook Pro in the pictures folder and I see a LRC catalog that I know shows up when you first download LRC but I of course don't use this one because I set it up to use the one on my external SSD. I opened it up out of curiosity and there showed up those 3 missing imports from in the beginning. Those 3 imports are also in my actual used catalog on my external SSD. 

So how do I correctly remove/transfer those 3 imports from the catalog on my Mac since I don't want anything there and since they are also on the external SSD where everything else is? No idea how they got there since I have always done everything the same since day 1 but I obviously messed up then. I can show whatever screenshots if needed.

 Thank you for any help getting this fixed correctly.
