Halo 5 Map Metadata - Null Names?

Hey there, I was pulling some metadata information from the Halo 5 -Maps endpoint and ran into a couple null "human" names in the results. Any chance these are just missing some values that could be filled in?

Here are the three ID's:

1. 5875580b-14aa-4cda-bc1f-a42732585364
2. b963a5ed-a8d0-4475-a47e-67430c56b3bd
3. d67fdcb9-6d9c-403e-960d-04202e19b244

And they are on this endpoint, with this doc page:

• https://www.haloapi.com/metadata/h5/metadata/maps
• https://developer.haloapi.com/docs/services/58ace18c21091812784ce8c5/operations/58ace18c2109180bdcacc42a

Judging by the image URL's, ("...map-images/arena/arena_maps_sustain_array04..."), these were all DLC arena maps of some kind, but I can't tell much more about them. I think one of them might be Tidal?

I am still experiencing the null names issue on the maps endpoint as described in the initial bug report
