Vector glyph orient not working

is this something I set prior to applying the standard glyph filter to my Cart2Spherical filter as the drop down menu for Orientation Array has no option and says “No orientation array”? I have ucomp (partial) and vcomp (partial) available, shouldn’t the option to plot the glyphs come from these objects, I can see them in the Coloring drop down menu? Not sure what the (partial) refers to. Thanks
