Field no accessable to specific groups, default value not working

[CAS_ual_TY]

Hello!

I would like to add a custom thread field that is only editable by certain user groups. If a group without access creates a thread in a forum using that field, it should not see it (works) and the default value should be applied (does not work). The field is a listbox. If a group with access creates a new thread, the default value is selected, if a group without access creates a new thread, it does not select that value (as stated already).

Is there any possibility to fix this? Or any possibility for a fix? Is this even possible or are there certain complications?

Anyways, thank you very much for that plugin. It REALLY makes a huge difference.
