Sorry but I can’t get to reproduce the bug from my side nor found a good reason for this bug :confused:

But still got some questions:

  1. Why delete and create instead of make change to the thing’s revenue? That can be a reason for the 10s delay when saving.
  2. Why the sum is in an input and is an integer vs a decimal 1 for the other figures?
  3. Is it possible that your action “Reset relevant inputs” is also reseting the dropdown’value Year?
