Export Project -> Import project: missing things: avatar, lists, project settings

Summary

When exporting a project and importing that same project in the same version of Gitlab (currently 18.2), a lot of things are suddenly missing. This behavior was not seen before in version 15.

Steps to reproduce

Click on Project -> Export Then Projects -> New Project -> Import -> From Gitlab Export

Example Project

File is 2025-08-29_13-15-759_ontwikkeling_ICTJOU_export.tar.gz It has

• avatar (already covered in Support avatar for project Export/Import (#516092))
• boards with a "doing" list
• Project settings (disabled features as Automate etc disabled)

What is the current bug behavior?

Avatar is not imported Lists in Boards are not imported Project-settings are not imported

What is the expected correct behavior?

Avatar is imported from file Lists in Boards are imported Project-settings are imported
