Set Tags tag not added in Test Tags

Hi all ,
Currently Iam using @{Test Tags}
Using for fetching the added Test Tags from setting section
However iam adding each test case and inside added [Tags] updated in @{Test Tags} before test case run.

But my scenario is iam using test template in suite setup using test template derived 6 test cases for each test cases iam using " Set Tags " keyword but set tags assigned tcs id not updating in @{Test Tags} due to that my analysis board showing no tagged test cases
