Hello,
I try to create 2 issues and an issue link between the two.
From JIRA it's working well, Issue1 blocks Issue2 and Issue2 is blocked by Issue1 automatically :



But when i try to do it from json :

I get blocks link for both issues :
From Issue1

From Issue2

I also tried to create the is blocked by link myself, but it provides the same result as clones.

I get is blocked by link for both issues.
How can i do it ?
Thanks in advance for any help.
