Serialized LocalizedString fields constantly resetting on prefab instances

I have this problem in my project where a serialized LocalizedString gets reset whenever I enter play mode but only if the component is attached to a prefab instance.

This can be seen in the following gif:

If I unpack the prefab, it works just fine and does not reset it when I enter play mode.
It is worth noting that no other serialized fields get reset, ONLY the LocalizedString field.

Furthermore, the prefab instance does get saved properly, as inspecting the .unity scene file shows the reference correctly being updated:


Alas, as soon as I enter play mode, the reference is lost and reset back to "None".
Why is this happening? Why can't I use prefab instances with the localization system? And how can I troubleshoot this?

 

Sounds like it could be related to this:

I sent a bug report through the editor with a very stripped-down version of my project where it still happens. Please let me know if you can reproduce it as well.

 

I also noticxed that in 2021.3.23 Serialized fields are reseted if this are used on component that is on prefab. It reset when going to playmode

 

Thats problem overall in that version of unity for all prefabs that use Serialzied fields, not only for localization tool. I didn't noticed the thread is only about localization tool.
