Toggle Button Stuck (New Record Rather Than Specified Filter)

Access 2010 64bit

I have an issue with the Access "Toggle Filter Button" being ticked whenever I open a form from a listbox (dbl click)...

[tblOrders] - (Key) [ID] - [Date] - [Consignee] (Text) - [OrderComplete] (Yes/No)
[tblPurchaseOrders] - (Key) [ID] - (Key) [AssignedID] - [ProductName] - [Weight]

This is just an example and it is not exactly what my database looks like however it allows me to explain easier.

tblOrders and tblPurchaseOrders are related One-to-Many ( tblOrders.[ID]->tblPurchaseOrders.[AssignedID]).

Anyways, I have a listbox on my primary form that lists tblOrders by ID, Date, Consignee and OrderComplete. When I first built the form and I bound the listbox to column 0 ([ID]) and created the event on double-click which the code looked like this:

Code:
Private Sub listOrders_DblClick(Cancel As Integer)
Dim stDocName As String
Dim stLinkCriteria As String
Dim intLinkID As String
intLinkID = Me.tblOrders.Value
stLinkCriteria = "[ID] = " & intLinkID
Debug.Print stLinkCriteria
stDocName = "frmManageOrders"
DoCmd.OpenForm stDocName, , , stLinkCriteria

Exit_Command23_Click:
Exit Sub
End Sub

Now, for whatever reason - either something I've changed or a bug somewhere... when I double-click the list item, it opens as a new record rather than the corresponding record. I noticed that the "Toggle Filter" button on the access ribbon was ticked so I unchecked it and it immediately switched to the proper record. Why does this happen and what (if common) changes can make this appear or work this way? I am a novice with Access and I am still learning VBA. I struggle with not knowing parameters by heart, although the syntax seems to be similar to other languages I've worked with.

I had somehow enabled "Data Entry" which is located on the Property Sheet of a Form under the "Data" tab. Apparently this mode removes your ability to actually filter values properly and is intended for what you'd assume it means - Data Entry.
