Geneos - Rules - Why does a computed cell retain its severity even if it goes outside the Active time?

For computed cells, there is a rule to define its value (let's call rule 1) and another to define the severity (let's call rule 2). Notice that if rule 2 has an active time, and once rule 2 goes outside Active time, the last severity of the cell is retained (normally, it should not have a severity outside active time). This is because a cell's active state is a logical OR of the active state of all the rules that affects the cell. Since the rule 1, which sets the value of the computed cell, is always active the the cell severity is not set to inactive when active time ends.

To remove the severity once outside the active time of rule 2, go to the Advanced tab of the rule, untick the "Active time affects cell" option. By default, it is set to true which implies active state of the rule affects the active state of the cell. If this setting is set false then the active state of the rule will not affect the active state of its target cells in any way.
