FDX filter not working

I am trying to extract cube data using FdxExecuteDataUnit however, the filter does not seem to be filtering any data. Any ideas what the issue could be? I am seeing multiple flow members in the data table. 

Is there also a way to do all base members for a dimension?

         Dim dt As DataTable
 
		     Dim cbName As String = "FinConsol"
             Dim ent As String = "E#124"
             Dim cons As String = "C#Local"
             Dim scen As String = "S#Actual"
             Dim time As String = "T#2025M1"
			 Dim view As String = "V#YTD"
			 Dim filter As String = "Origin='Import' AND Flow='EndBalInp' AND Account = 'NetInc' AND UD7 = 'GL_Load'"
						
						
            dt = BRApi.Import.Data.FdxExecuteDataUnit(si, cbName, ent, cons, ScenarioTypeId.Actual, scen, time, view, True, filter, 1, False)
