"Index exceeds the number of array elements" Error with Version 2.3

Hello! I tried the new version of the function, but now I'm getting this error, and I have no idea where it's coming from. I have created a minimal example with a small plot, a .mat file with the data, the .fig file with the plot and an .m file to run everything. Do you have any advice on what I am doing wrong?
