"Blocks" and "Is blocked by" relation seems to be inverted

[Arnaud ROYER]

Hello. Lastly, I have seen that some links between tasks seem to be broken in the Advanced Roadmap. In this example, the right order is Task 1 > Task 2 > Task 3.

In other words:

• Task 1 blocks Task 2
• Task 2 is blocked by Task 1 and blocks Task 3
• Task 3 is blocked by Task 2

In the Plan view, it's completely messy. The lines are in the wrong direction.

Did I miss something or is it a bug?

@Arnaud ROYER, 

Check to see how your issue linking is configured in your system administration. Navigate to Administration -> Issues -> Issue Linking.

For the Blocks relationship, please confirm that your outward description is blocks and your inward description is is blocked by.

That was it! Thank you so much, it made me crazy.

I don't know why but the relation switches regularly. I have to change it back manually every time.

Any idea why it changes by itself?

I would raise a ticket with Atlassian.. it appears other people are seeing the same issue - https://community.atlassian.com/t5/Jira-questions/quot-Blocks-quot-and-quot-Is-Blocked-By-quot-Inverting/qaq-p/2254922.
