You have several issues linked to a single initiative, epic, etc. You need to change the link type to be consistent with another project or team.
Create a new, blank structure and add 2 folders. Add the parent initiative to both folders.
Add an Extend with Issue Links generator to each folder:
- First Folder - Link type = the current link type
- Second Folder - Link type = desired link type
(Make sure the Allow changes via Structure option is checked for both generators.)
Select all issues under the generator added to the first folder, and drag them to second folder, as children of the initiative.
Structure will automatically replace all the old links with the new link type.
