The script Waterfall  doesn't work anymore

Hi all, 

Do you notice that the script Waterfall  doesn't work anymore after the release L2022.09 or L2022.10 ? The summary columns are not calculated and the "layout" don't work. The console give this error message : "Cannot set properties of undefined (setting 'isSum')". Can someone help me with this problem?  

thank you in advance,
