I am having a problem in resizing my 2 volumes on my Macbook Pro (2016, 1TB HDD) using Paragon Camptune. I have used this app before and it worked well.

At the moment, when I try and resize the volumes I am getting this error message: "Resizing operation failed. No free space (cannot create partition of requested size)". See screenshot:



However, looking at the volume sizes in Camptune, it does appear that my "Macintosh HD" does have free space - 100.93GB to be exact. See screenshot:



I tried to move just 25GB or so of space to the Bootcamp partition, but am getting this error message. Any help appreciated!
