Why does the VEX Gamepad Button block in Simulink shows question marks?

When I select Channel 8 Down configuration on the VEX gamepad Button block, the block image changes to three question marks.

This issue is only within the image display of the block mask. The block will work as intended and produce no errors when simulating or deploying models to hardware.
In order to fix the image display you can do the following:
In the MATLAB command window, execute:
>> matlabshared.supportpkg.getSupportPackageRoot
Eg: C:\ProgramData\MATLAB\SupportPackages\R2018b\
Navigate to the following path >> SupportpackageRoot\toolbox\target\supportpackages\vexarmcortex\blocks
Eg: C:\ProgramData\MATLAB\SupportPackages\R2018b\toolbox\target\supportpackages\vexarmcortex\blocks
Replace the file "vexarmcortexlib.slx" in that directory with the one attached to this post.
