Issue with updating Key Schedule

I am having trouble with the Key Schedule node from Archi-Lab. It appears that I can create a Key Schedule from data in an Excel file, but I am unable to update the Key Schedule if i update the Excel file after the initial run. Is that expected behavior for that node?

Hello everybody,
I’m struggling with the same problem.
I created a key schedule with Archi-Lab.
If I want to update the key schedule, some rows even disappear.

Does somebody has any idea?
