Why are there so many duplicates on my phone after using Link2SD

I have noticed that the internal storage of my tablet is filling up even though I have tried to link as many of the apps as possible to the SD card using Link2sd. I did a quick search for duplicates using Search Duplicate File(Super). What I found was that 1117 files where duplicated in both the /mnt/internal_sd/ and /mnt/external_sd directories. Any idea why this has happened, and how I can free up this space?

I have searched both paths and none of them are symbolic links to the other. These are actual duplicates of the files.

How many CM13 based ROMs do we got on here anyhow?

This Spaceballs scene comes to mind. ;)

Before I go digging in and determining what the difference between each of these CM13 based ROMs - I was curious if any of you might be more acqauinted with these and willing to offer some insight. Please forgive my ignorance, but I am curious as to what the main differences between each of these ROMs. From what I can tell, some of the 'unique' features of some of them, are also unadvertised features of the other ROMs...?

Quick list
* AICP
* Bliss Rom
* Beanstalk v6.0.6

I will continue digging and will document my findings here.
