How to remove missing systemd units

I'm having trouble figuring out how to remove systemd units that no longer have files. They still seem to linger in the system somehow.

The old broken units I am trying to remove:

core@ip-172-16-32-83 ~ $ systemctl list-units --all firehose-router*
  UNIT                       LOAD      ACTIVE SUB    DESCRIPTION
<E2><97><8F> firehose-router@02.service not-found failed failed firehose-router@02.service
<E2><97><8F> firehose-router@03.service not-found failed failed firehose-router@03.service

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

2 loaded units listed.
To show all installed unit files use 'systemctl list-unit-files'.

The files do not exist, yet a reload still has these units lingering:

core@ip-172-16-32-83 ~ $ systemctl list-unit-files firehose-router@02.service
core@ip-172-16-32-83 ~ $ sudo systemctl daemon-reload
core@ip-172-16-32-83 ~ $ systemctl list-units --all firehose-router*
  UNIT                       LOAD      ACTIVE SUB    DESCRIPTION
<E2><97><8F> firehose-router@02.service not-found failed failed firehose-router@02.service
<E2><97><8F> firehose-router@03.service not-found failed failed firehose-router@03.service

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

2 loaded units listed.
To show all installed unit files use 'systemctl list-unit-files'.

There are no files related to them that I can find:

core@ip-172-16-32-83 ~ $ sudo find /var/run/systemd -name "*firehose-router*"
core@ip-172-16-32-83 ~ $ find /etc/systemd/ -name "*firehose-router*"
core@ip-172-16-32-83 ~ $ find /usr/lib/systemd/ -name "*firehose-router*"
core@ip-172-16-32-83 ~ $

So how do I get rid of these?
