Welcome to OSM, and kudos for the valuable work! Thank you for helping create a better map on OpenStreetMap.

For naming features, our practice is to avoid abbreviations, so the names you added, for example, should be "Filbert Street" rather than "Filbert St". 

Depending on which map layer you might be using, the map renderer will take care of the appropriate abbreviation for you.
