/control-construct/logical-termination-point{1234}/layer-protocol{1}/air-interface-pac/air-interface-configuration/air-interface-name{test}

now for this path in confd_cli if I will give,

show running-config control-construct logical-termination-point layer-protocol air-interface-pac air-interface-configuration
control-construct logical-termination-point 1234
 layer-protocol 1
  air-interface-pac air-interface-configuration air-interface-name ""

It is coming properly,
If I am giving only till air-interface-pac then it is giving output as “no entries found”

show running-config control-construct logical-termination-point layer-protocol air-interface-pac 
No entries found.

why this is happening ?

Hard to tell without the YANG model implementation of the nodes involved. If you post the YANG model parts that are involved it will likely be possible to debug the issue.
