Two Apps turning on the same Light causes error

Both the below apps are attempting to control the "Front Entrance" Light.

When below the error is created, the "L01a Front Entrance Lights" rule has turned on the Front Entrance Light and is in the 20 minute delay before turning the light off.
AND
The RM Rule "G01 Safety GarageOpen_Vehicle_Dark__LightsOn" runs and attempts to turn on the "Front Entrance Light" (which is already on).

Sometimes the "Front Entrance Light" does not turn off after the 20 minutes (have to check this more as it didn't happen when I was watching the processes).

Is this something I should avoid? Or perhaps test with the Garage light rule?

Tnx
John
