ASP.Net Formview skipping records when paging - asp.net

Question

I have a formview that binds to an Entity Framework datasource using the following code:
Private Sub LoadFormviewData()
Dim ctx As New SNOTEntities
Dim RepCalls = ctx.SNOT_RepCall_view
Dim strSQL As New StringBuilder
strSQL.Append("select * from SNOT_RepCall_view where DateInput >= '")
strSQL.Append(Startdate.ToShortDateString)
strSQL.Append("' and DateInput <= '")
strSQL.Append(EndDate.ToShortDateString)
If IncReviewed = "N" Then
strSQL.Append("' and Reviewed = 'N'")
Else
strSQL.Append("'")
End If
strSQL.Append(" order by IssueID")
Dim calls = RepCalls.SqlQuery(strSQL.ToString)
FormView1.DataSource = calls.ToList
FormView1.DataBind()
If 1 = 1 Then
End If
End Sub
Using the AllowPaging=true I find that it skips every other record when paging. I am new to EF and not that good at ASP.net so forgive me if you require any more info.
I use the IndexChanging and Indexchanged events to save/populate fields that are outside of the formview (too much code to post unless requested)
I have confirmed that the correct amount of records are in 'calls' and that they make it into the Formview datasource. It just skips every other record when paging. Have stared at this code for days. Any help/suggestions welcome.

The pagertemplate is commented out as part of my testing leaving just the default version.
