I am using Classic Version:
I have lost the ability to create an Epic within an Epic. There must have been a recent update that closed that loop. In the past, I could create a Story within an Epic and establish a link. Once the link was established you could go back into the Story and change it to an Epic and then that jira story (Now an Epic) would maintain the relationship to the Parent Epic.
Now its breaking the relationship even though the message says the relationship wont be lost in Classic Projects. 
Is there a setting that needs to be turned on or is there another work around. My previous ones i have completed are still maintaining their relationship.

Any help would be greatly appreciated.
Thanks, Matt M
