My sheets have random wrong results with basic add and subtraction formulas. I can correct by replacing the exactly same formula from another sheet but it makes the calculation unreliable.
The formula: =E218+G218-H218-F218 which should return 0 but it returned -39 insteads.
I removed all importrange posible causes by Copy value of all imported ranges. I also removed protection, unnecessary sheets and unrelated ranges, named it 'Basic version'.
This is one of wrong result cell, and it happens randomly. https://docs.google.com/spreadsheets/d/1jPbSJU0iyn6LjuRRwjc5x7Hy7sLL8CxmiXa7pdXXqEA/edit#gid=265206709&range=I218
Feel free to edit, I made a copy of it.
Thanks.
