Constance values in read only mode although user has superuser access and sees the save button

[EBB5]

Hi,
Our team has the issue that when someone wants to edit a constance value, the field is read-only although the user has access and has also at the bottom a save button. Hitting the save button also gives the message that the settings are saved.

In the behind html there is the disabled tag present.

Strange thing is that some users can have it and others not and that for a user that has it, for example 2 hours later it works again.
We use a LB with 2 servers behind it, but in case it is not working I already tested the sending of the user its traffic dedicated to server 1 and then to server 2, and for none of the 2 it works. Comparing the code on both servers did not show any differences.
We currently use django 5.0.13 and django constance 4.0.0.
Is there somebody that experienced this same behavior ?

Kind regards,
Steven
