GUI error when loading saved 3D project file without IP data

Platform : Windows
Version : 3.6.4
Error Message : Error in loading project: ‘Data array (cellType) not present in this dataset.’
Problem Description : When importing a saved .resipy project file for a 3D ERT&IP dataset without IP data included in the inversion, the ResIPy GUI throws the above error. The error does not occur if IP data is included in the inversion. The error is specific to 3D datasets; 2D datasets load without error, regardless of IP inclusion. The error only appears in the GUI; using the API, p.showResults() works without issue.
How to reproduce it : Import 3D Syscal ERT&IP dataset, exclude IP data, invert the data, save the project, load the project in the GUI, error message appears.
