Can't find Pi Point after create

I have C# application that creates a new Pi Point using the code based on  PI-AF-SDK-Basic-Samples/CreatePIPointsExample.cs at master · osisoft/PI-AF-SDK-Basic-Samples · GitHub 

The point seems to be created ok - here's a screen grab following a tag search in SMT:

My problem is, when my same C# application searches for the newly created Pi Point is doesn't find it. The code for the search is as follows:

       

private static List<PIPoint> GetPiPoints(PIServer piServer)
        {
            var criteria = GetCriteria("61");
            var foundPoints = PIPoint.FindPIPoints(piServer, criteria).ToList();

            criteria = GetCriteria("63");
            foundPoints.AddRange(PIPoint.FindPIPoints(piServer, criteria).ToList());


            criteria = GetCriteria("64");
            foundPoints.AddRange(PIPoint.FindPIPoints(piServer, criteria).ToList());


            return foundPoints;
        }

private static List<PIPointQuery> GetCriteria(string location)
        {
            List<PIPointQuery> criteria = new List<PIPointQuery>();

            PIPointQuery whereClause1 = new PIPointQuery(PICommonPointAttributes.Location1, OSIsoft.AF.Search.AFSearchOperator.Equal, location);
            PIPointQuery whereClause2 = new PIPointQuery(PICommonPointAttributes.PointSource, OSIsoft.AF.Search.AFSearchOperator.Equal, "o");

            criteria.Add(whereClause1);
            criteria.Add(whereClause2);

            return criteria;
        }

So, my understanding is that this should find all points that have a "location1" attribute value of 61, 63 or 61 AND a "pointSource" of "o" - I have tried uppercase and lower case "o"

From the screenshot, you can see that this is the case for the newly created "Kuba_99x" tag yet it is not found in the search, although thousands of other existing tags are.

Any ideas where I went wrong please?

The Pi code was actually fine. Problem was, my code was filtering the newly created record after the selection.
