Variables with delay and red square

Hello,
In my project I have the a problem with input and refresh with a the variables of the Zenon.

When I set the new value in the variable in the field, the value is update in the variable of the PLC, but not show me in the screen. In addition, the alarms list, doesn't generate in the moment, has a delay to show the alarm in screen.
Even though, the Zenon it is working, but with many delay the screen to open.
All the variables with problem has the red square.
I tried to restart the program and PC, and change the driver NG Beckhoff
, but not returned to work yet.
