Android Question What Additional Libraries should I keep or delete?

I just upgraded from B4A 9.01 to 11.5 and am running into a bunch of problems with the first project I tried loading (I will make other posts for the other problems).

But for this post, I have noticed that there are files in my "\AddLibs" directory that are also in the B4A 11.5 "\Libraries" folder.

So, my first thought is that some libraries that were external, are now internal, hence the duplicates.

But I specifically want to know:

1. What files should I delete from the \AddLibs folder
2. Could there be problems with using the newer version of a library in the internal libraries directory and I should instead use the older AdditionalLibraries version?

Here is a screenshot of the files with the same names:
