If you choose parallel cables with a common overload protective device then an orange warning/information appears
The warning with the text "When using cables in parallel with a shared protection, it is important that each and every cable withstands the let-through energy specified in the manufacturer data of the protection" is in fact a statement that this may be a problem, but that it cannot be checked using EL-VIS as we do not have product-specific data on different protections, which is required to check this.
If you have parallel cables with a common protection for both (or more) cables, the cable area is often smaller in relation to the size of the protection device than with just one cable, which increases the risk that the transmitted energy of the protection device is greater than what the cable can withstand.
Example of how this warning/information looks in EL-VIS Cable:
