5G Home Internet - ID Field in IP header

I was able to get my connection going by eliminating the use of the ID Field within the configuration of the Cisco routers.  Therefore, the ID Field is being corrupted by the T-Mobile router/service.  My connection through the T-Mobile 5G Internet router is using a Cisco SDWAN Router that creates IPsec tunnels to my work locations.  Has anyone in the community or at T-Mobile seen this issue?  And if so, how can T-Mobile correct the problem?  Thanks.
