I clicked at J7 and selected Conditional Formatting/Manage rules... It showed one rule but the rule was applied to $N5:$N$100. The rule had nothing to do with column J. Why did the rule show up at J7 (in fact J5:J100)? When I clicked on Find & Select/Conditional Formatting, nothing in column J was selected.
The cells in column N have the same rule. However, if I delete the conditional formatting rule in column J, the cells in column N will lose their rule.
