Assuming you are using some flavor of InRoads. Are you using the View Horizontal Annotation or just View Active Horizontal?
These come from the XIN - possibly from the default style. Check on the View Horizontal Annotation dialog box, the Styles tab. Here, each point type can be assigned a style. If you change the style in use so that the font used is Civil, which I think is one of the delivered InRoads Fonts, you will get triangles or circles, both with smaller inscribed circles, centered on the insertion point. Note there are also two checkboxes for changing some of the point symbology behaviors.
Finally, there is a new setting that allows the display, annotation and stationing of alignments as drawn and edited. There are other posts about how to make it work - some of these settings can affect how that setting operates.
