There are 2 separate library versions that can be installed and it is only required to install one or the other. 
The difference between the libraries is simply the GUI size of the plugin window that is stored within the preset files. 
Initially the presets loaded the GUI at 1.3 scale which for a larger display of 2K or above this was an ideal resolution however on smaller displays such as macbook or with DPI scaling increased this could cause the plugin window to not fit the display so a 1.0 scale GUI option is now also included. 

If you need the smaller GUI display install the NKS files from the 1.0 library. 

If you would like the increased GUI size install the NKS files from the 1.3 library

You only need to change the NKS files for this to take affect, no need to replace the database files.
