Delta V permissions issue

Hello all, New to this forum. Ive been working with Delta V for many years. Every now and then something comes up on our system that I have never seen before. Utilizing a simply data entry push button setting a control module register to either a 1 or a 0, I get the attached error.
1) Yes, the control module area is assigned to the alarm and events of the workstation which has been downloaded.
2) There should be no need for special parameter/ field security settings
3) More then enough DST's for the workstation.

This is a version 12 system. Now, I have not yet shutdown and re-started the workstation or checked that the workstation is in time sync with the rest of the system. Again, something I haven't seen or experienced before. What am I missing here? Thank You in advance.
