Do you have a selection set also applied in the view filter. Are the points 3D or 2D - if 2D you may have the Do Not Display setting applied in the view filter (at bottom in display settings)
Could also be that you have CAD Points turned off in your view filter - go to advanced settings in the View Filter and look at the CAD Data section and check that points is turned on
If these fail come back to us or as Tim requested share your file and we can take a look.
Are you sure the Layer is ON that the points are on - if the All filter is working but other Filters not then you have some additionalView Filter control being applied

My guess is that it is one of these
