MySQL TEXT field to unbound Access 2007 textbox

I have an Access front end client working on a MySQL backend server. I have one MySQL field that populates an unbound textbox via a recordset lookup. When the data it retrieves gets large, the data in the textbox truncates in strange ways. Sometimes the last few characters at the end of the field data post, sometimes, the last 200 or so characters post.
What can be happening here? The code that populates the form is attached.
The textbox is named txt_count_notes. Thanks

Dim dbs As Database, rst As Recordset, strSQL As String, vSales_Order As Long, X
strSQL = "SELECT DISTINCT receipts.id, receipts.customer_id, receipts.sales_order_id, receipts.count_correct, receipts.count_notes, "
strSQL = strSQL & "receipts.parts_damaged, receipts.parts_damaged_notes, receipts.order_size_id "
strSQL = strSQL & "FROM receipts WHERE receipts.id = " & TempVars("record_id")

Set dbs = CurrentDb
Set rst = dbs.OpenRecordset(strSQL)

rst.MoveLast
X = Nz(ELookup("complete_date", "wtbl_receivers", "receiver_id=" & TempVars("record_id")), 0)
If X <> 0 Then X = -1

With frm
    .cmb_customer.BoundColumn = 1
    .cmb_customer.Value = rst!customer_id
    .cmb_customer.BoundColumn = 2
    .cmb_order_size.BoundColumn = 1
    .cmb_order_size.Value = rst!order_size_id
    .cmb_order_size.BoundColumn = 0
    .chk_count.Value = Replace(rst!count_correct, 1, -1)
    .chk_damage.Value = Replace(rst!parts_damaged, 1, 0)
    .txt_count_notes.Value = rst!count_notes
    .txt_damage_notes.Value = rst!parts_damaged_notes
    
End With

dbs.Close
Set rst = Nothing
Set dbs = Nothing
