Create Sub-Task under Stroy that link to Epic

[Guy Levkowitz]

Hi,

We have Epic that under it link list of Stories, when we press on one of the Stories Setting Icon and it gives the list of options , we create Sub-Task,  the Sub-task that created is automatically Link to the Epic insted of the Story that i have did the action on , why ?   

when we create Sub-Task under Story Directly from the More option , it link the Sub-Task to the Story .

So my Question is - does it is some kind of "Bug"  or is it the way it should be ? 

we are working on Jira version 6.1.7 and Agile plugin  6.6.80

wait for any answer.

thanks
