Specificlly, my certificate says, "Instrument
airplane, helicopter, and glider".

Please check your certificate again and post the exact wording
including all punctuation. According to the FAA database, and
assuming I found the correct person, it should say:

Commercial Pilot
Airplane Single and Multi Engine Land
Rotorcraft Helicopter
Glider
Instrument Airplane and Helicopter

There is no glider instrument rating.
