Help - BPT sent to KNC Balancer Pool contract address

Hi. Help needed. I was trying to join a KNC Balancer Pool on YFV. On Balancer, I converted some KNC into a BPT token. The BPT token was on my Metamask but not recognized by the Balancer pool for some reason. So I copied the KNC Balancer Pool address and used Metamask to send the BPT in my Metamask to that pool address. The transaction went through according to Etherscan, but it is not on Balancer or in my Metamask. Any suggestions? Any assistance would be greatly appreciated.
