Error at Outlier detection (ART-based) preprocessing step

Hello everyone,
First post for me on this forum. It's been very useful to read you all for quite some months now. Thanks to all of you.

I'm running an event functional whole-brain analysis, that's been proving to work well from beginning to the end.
I wanted to come back to the Setup step and add and Outlier detection preprocess step then re-do my analysis.
Though, when launching this step, I've got the following error:

I've got an event design with 39 subjects, each performing 3 sessions. Each subject has 368 scans, each has the same amount of onsets and no onset times beyond the end of the scanning session.
Besides the setup was constructed from the import function that loaded 39 spm.mat.
What do I get wrong ?

Cheers
