I don’t think IDA actually sends metadata about ‘sub_’ functions to lumina servers (afaik a few prefixes are excluded). You can verify this by querying your database: select * from funcs where name like ‘sub\_%’

After experimenting with a brand new db file, I've determined its not giving them a "name" in the db.

$ psql -U user -d postgres -f lumen/schema.sql

1, Start Lumen

$ pg_dump postgres > postgress_1.sql

COPY public.funcs (id, name, len, db_id, chksum, metadata, rank, push_dt, update_dt) FROM stdin;
\.

1, Open mirc-7.00.exe
2, Analyze
3, Find function sub_5443B0
4, Right click on function name
5, Click Lumina
6, Click Push functions metadata

Output window:

1 new out of 1 (1.000000 ratio)

$ pg_dump postgres > postgress_2.sql

COPY public.funcs (id, name, len, db_id, chksum, metadata, rank, push_dt, update_dt) FROM stdin;

\.

1, Find function sub_445B50
2, Rename into ndocommands
3, Right click on function name
4, Click Lumina
5, Click Push functions metadata

$ pg_dump postgres > postgress_3.sql

I opened postgress_3.sql in a text editor and found this:

COPY public.funcs (id, name, len, db_id, chksum, metadata, rank, push_dt, update_dt) FROM stdin;
1		18373	1	\\x...	\\x...	10	2021-04-29 01:14:30.991433-04	2021-04-29 01:14:30.991433-04

Fixed via DELETE FROM funcs WHERE name ='';
