uniquetol give an "Unknown option specified" error when I run it on a cluster

I have code that I'm trying to run on a cluster. I've tested my code on a local host and it works fine, but if I run it on my cluster the MATLAB built-in function `uniquetol` errors out.
I call my function with the following script:
cluster = parcluster('MyGenericClusterProfile') % NOTE: if I change the cluster profile to 'local' I don't have any errors
job = createCommunicatingJob(cluster);
job.numWorkersRange=[1 1]; % Trying to get it to work on a single node before I scale up and add communications functionality
% Lots of code building and setting up arrays, some of which are
% gpuArrays but none of the ones in uniquetol are gpuArrays
class(A) % returns 'double' in Task1.diary.txt
[C,IA,IC]=uniquetol(A,1e-4,'highest'); % According to Task1.out.mat, generates a MATLAB:uniquetol:UnknowOptions ParallelException when run on cluster
If I comment out the 'highest' option of uniquetol while running on the cluster, my code runs without Exceptions but I need that option to get the correct run-time results. Why does my code behave differently depending on where I run it, and how do I make it behave correctly?
