[Import Document] Changing type of multiple observables in workbench removes an observable

[debelyoo]

Description

I'm importing a PDF with the import-document connector. A workbench is created with the extracted entities. When I change the type of two (or more) observables (e.g. from File to Artifact), the observable that has been modified first is removed from the workbench.

Environment

1. OS (where OpenCTI server runs): Ubuntu 22.04
2. OpenCTI version: OpenCTI 6.2.15
3. OpenCTI client: frontend
4. Other environment details:

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Import PDF document with observables (see attached file)
2. Open the corresponding workbench (created by the import-document connector)
3. Change the type of one observable from 'File' to 'Artifact'
4. Change the type of another observable from 'File' to 'Artifact'

Expected Output

The two observables should have the new type 'Artifact'

Actual Output

The first modified observable is removed from the workbench.
