Identity ID generated for "The MITRE Corporation" inconsistent with what is provided by MITRE

[n0p2]

Description

The issue is related to Identity ID for "The MITRE Corporation". I encountered two IDs and they are inconsistent.

1. When generated by using the pycti.Identity.generate_id, the ID is identity--f11b0831-e7e6-5214-9431-ccf054e53e94;
2. When found on the internet, the ID is identity--c78cb6e5-0c4b-4611-8297-d1b8b55e40b5

So the question is,

1. Why are there two inconsistent ones for the same identity?
2. What are some acceptable mitigations in order to load MITRE ATT&CK?

Environment

pycti 5.3.17

Actual Output (or pycti Output)

Steps to create the smallest reproducible scenario:

# Code 
from pycti import Identity
mitre_id = Identity.generate_id("The MITRE Corporation", "organization")
print(mitre_id)

# Result
identity--f11b0831-e7e6-5214-9431-ccf054e53e94

Expected Output (or Internet Expectation)

It seems that the "correct" ID corresponding to "The MITRE Corporation" should be identity--c78cb6e5-0c4b-4611-8297-d1b8b55e40b5.
