SD Cloud shows the deletion of system services for st0 interfaces for newly imported IPSec VPNs. The preview configuration looks as below.

This is a bug. SD Cloud should not be deleting the host-inbound-traffic configuration for the st0 interfaces when the IPSec VPNs are freshly imported from the device.
A permanent fix for this problem is available in the 24.4 release of SD Cloud which will be available by end of March 2025.
Till then, the customer can follow the below workaround.
