Connections are sent (to old target group) although disabled
In this case, you have old pending connection requests on LinkedIn that were only accepted now.
You can find the pending connection requests here:
https://www.linkedin.com/mynetwork/invitation-manager/sent/
If these are accepted after weeks or months, the chat shows the date and time of acceptance, not the date of the connection request being sent.
We recommend withdrawing connections after 5 days.
