Duplication folder when '/' are present in GitLab milestone name

Affected version : xsquash4gitlab 8.0

Steps to reproduce & Observed behaviour

in GitLab, having a project and several issues, some of which are associated with the milestone

1/ In Squash, create a first synchronization by milestone without any additional filter (I have the State Opened filter, but I don't think it matters): issues not associated with the milestone are therefore in the scope and will be created at the root of the target folder; 2/ Create a second synchronization by milestone, adding a filter to exclude issues not associated with the milestone (Milestone/At least one/Any); 3/ Create a third synchronization from a GitLab project where there are no issues not associated with the milestone.

Let the first round of synchronization take place: everything is in order: each target folder is created, as well as a single folder corresponding to the milestone, and milestone-related issues are created in the said folder.

In GitLab, associate a new issue with the synchronized milestone, then wait for the next round of synchronization:

1/New folders are created in the EDP 2025/02/08 tree structure, and the newly associated issue is created in the '08' directory. 2/ no new folders are created, and the issue is in the original directory 3/ same as 2/.

Expected result

No new directories need to be created.
