error - ('Additions 10/28/19 by Tor Wager to add output to within-ss stats need checking to avoid code conflicts');

[belrodis]

in the script mediation_toolbox/mediation.m

catch
disp('Additions 10/28/19 by Tor Wager to add output to within-ss stats need checking to avoid code conflicts');
end

what could cause this error/message? I am running a mediation_brain_multilevel.
Could it be that I added a second-level moderator with an L2M option (v = [34; 45; 23; 67; 34; 78; 90])?

Thank you
