This flashing means that there is a strong phase shift between the voltage and the rated current on your network.
If your installation is single-phase, this indicates a strongly inductive load on the electrical network (swimming pool pump motor, powerful halogen lighting...), and has no impact on the correct functioning of your smart load shedder.
If your installation is in three-phases, please check that the power supply of the load shedder is done via the same phase as the line on which you have installed the current transformer.
