Trouble Removing ENIs eni-0ab2e473c30b113d2 and eni-02985b14cbc402722

It appears that these network interfaces are "stuck" and I'm unable to remove them, therefore can't free (delete) the resources (VPCs, subnets, etc.) that are using them. We've been unable to track down what might still be using them. Can you confirm they are (or aren't) stuck, and if not, point us in the right direction on what's using them? Thank you.
