Need help installing TE conn tab into connector

Interconnect Rectangular Connectors

Hello,

These are TE AMP parts. I am trying to insert conn tab 17-1718348-1CT-ND into connector 17-1-1703498-1-ND. When I insert the tab, it barely goes into the connector even when I apply much force. I can never get the tab to fully enter or lock into the connector. I notice a purple locking piece down in the connector. Even when I push it to the right, the tab still won’t go in. Should I be removing the purple piece somehow? Do I have the wrong tabs?
