Can you show pictures of your connectors with the wires in them? Again, without the wires, they won't click together at all. They will only click together and be hard to pull apart once the wires are in place.

Some teams will push the wires with the pins into the connectors but not enough for the metalic crimped part to fully snap over the metal spring in the connector. If this snap hasn't happened, then the springs won't hold the two mated connectors together.
