On the Subject of Simon Simons

Was there a manufacturing error while making Simon Says modules to make this thing?

This module contains 4 Simon Says modules. To defuse this module, 5 inputs from any of the Simons need to be received and correct. You will need to press buttons in the correct order. Some steps may specify specific buttons in specific cardinal directions. These can be found in Appendix S2. The color that flashes determines the column, and the number of strikes determines the row. If you wait enough time after pressing a button, the flashing sequence will restart and your input will be reset.
