@G-Laliberte, Unfortunately, I couldn't replicate the bug. I tried something in the commit c833331b8cdc18f2576fbcfad507ddead08f8c49. Can you give it a try and tell us if it failed/worked?

Also, what is the matlab release that you are currently running umIT?

Thanks,

[G-Laliberte]

I downloaded the new Matlab2022b, tried with the new files and it works, thank you!

I was using Matlab2021b.
