Hi There,
I cant think of any reason why this would be happening, but I did have a few more follow up questions for you to get a bit more context here?
First, how are you calculating a break? Are you pausing the Timer and Starting again after the break is complete?
When you say you are changing the Duration in the table, are you changing it on the screen? Or completely Exporting/ Importing the table?
If you are Changing the value on the screen, are you refreshing the grid after saving? The Grid wont refresh on save by default.
This does sound like an unusual one though, I might need to get a support rep to reach out.
Thanks!
Regards,
Ben
