Add_Plan_Entry creating test runs with all test cases selected even though case_ids list is passed in

[beaudetious]

Describe the bug
When creating a test run under an existing test plan using add_plan_entry, the newly created test run has all test cases selected instead of the values assigned to the "case_ids" property in the body.

To Reproduce
Steps to reproduce the behavior:

curl --location 'https://ctssoftware.testrail.io/index.php?/api/v2/add_plan_entry/314=null' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic REDACTED' \
--header 'Cookie: tr_session=ae91f9e1-8198-4329-b7b1-0b6ceccf0486' \
--data '{    
    "suite_id": 9,                      
    "assignedto_id": 4,                 
    "include_all": true,                
    "name": "Tester 1 Test Run 9/9/2025",  
    "runs": [
        {           
            "include_all": false,       
            "case_ids": [131838,131845,131890,13920,2904,2915,5211,5238]         
        }
    ]
}'

Expected behavior
The new test run will have only 8 test cases assigned to it.

Additional context
When I make a similar call with the add_run endpoint and use the same "case_ids" property value, the new test run is correctly selecting 8 test cases.

curl --location 'https://ctssoftware.testrail.io/index.php?/api/v2/add_run/2=null' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic REDACTED' \
--header 'Cookie: tr_session=ae91f9e1-8198-4329-b7b1-0b6ceccf0486' \
--data '{    
    "suite_id": 9,                      
    "assignedto_id": 4,                 
    "include_all": false,       
    "name": "Tester 1 Test Run 9/9/2025",
    "case_ids": [131838,131845,131890,13920,2904,2915,5211,5238]
}'
