Error when displaying a new kill chain created in Matrix View

[lightw1s3]

Description

The TTPs associated to a newly created kill chain are not correctly displayed in the section Knowledge > Attack Patterns > in Matrix View.
In addition to having the main ones, MITRE or associated and DISARM, it is necessary to create a new Kill Chain where the Mitre TTPs are reused.
However, when visualizing the matrix, not all the phases of the kill chain created appear.

Environment

1. OS (where OpenCTI server runs): docker
2. OpenCTI version: 6.3.11
3. OpenCTI client: frontend

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Go to Settings > Taxonomies > Kill chain phases and create a new kill chain called operator-chain in which 3 phases have been defined

2. The following TTPs are used as examples to associate them as examples to each of the phases created:

• T1595.001: Relates to phase1.
• T1053.002 and T1217: Relates to phase2
• T1119: Relates to phase3

3. An example Threat Actor (group) is created, with the TTP section empty and access to its Knowledge > Attack Patterns > Matrix View section.

4. And as you can see in this last capture, the first phase does not appear.
   

Expected Output

It is expected that this image will show the complete new kill chain, i.e. with all the associated TTPs.
