Checkbox to Hide Fields not working

[KerryAustin]

I have a subform in a navigation form where I placed a bound checkbox, when selected will hide several fields I do not want the user to fill in. It was working several days ago and now it is not. I do not get an error message or anything that alerts to an issue. In the After Updatre Event I have the following code:

'Hides Fields based on Checkbox
Private Sub DelayInfoOnly_AfterUpdate()
If Me.DelayInfoOnly = True Then
Me.txtMRN.Visible = False
Me.txtAssessionNumber.Visible = False
Me.txtCaseNumber.Visible = False


Else
Me.txtMRN.Visible = True
Me.txtAssessionNumber.Visible = True
Me.txtCaseNumber.Visible = True
End If
End Sub

I noted at the botom left corner of Access Screen when I click on the checkbox, it shows the label and then states it is calculating. Appears to be doing something but does not hide the fields. I was just in the process of spliting the database, had made a copy/backup. at first the split was working as well. Now the backup and split is not. Any idea why this wouldn't work?
Here is a copy of the Form.

I found the issues, I had macros disabled under Trust Center Settings.
