Error when accessing Intrusion sets on a specific platform (missing data)

[SouadHadjiat]

Description

Can't access currently intrusions sets on Filigran platform : https://filigran.opencti.io/dashboard/threats/intrusion_sets
The issue is due to a missing Sector targetted by an intrusion Set of the list (the relationship still exists but the Sector is not found). It only happens in this case, and can also happen for Malwares, Campaigns, and Threat Actors cards views.
It happens also for malwares, just need to scroll a little and the error appears https://filigran.opencti.io/dashboard/arsenal/malwares
