LDF Log file is 30.6 GB - Initial Size somehow set to 30 GB and it can't be changed

When one of my sql databases was set up, the default initial size got set to 30GB (!). I have tried shrinking the log file, but it won't shrink to below about 30GB. I have tried changing the default initial size to 50MB, but it reverts back to 30 GB when I take any actions. I have tried backing up the database and restoring it from the backup...and it re-incorporates the 30GB file.

I have tried the following SQL query but it gives the following error. Note that I tried limiting it to a single user.

SQL:

USE [dbname]
DECLARE @FILEID int

SELECT @FILEID = file_id FROM sys.database_files WHERE type = 1

DBCC SHRINKFILE(@FILEID)

ERROR:

Cannot shrink log file 2 (dbname_log) because all logical log files are in use.

(1 row(s) affected)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

I'm stuck. I've had one SQL vendor try to help, but he's stuck. Help!

I ran the code in this thread:

https://www.experts-exchange.com/questions/22392154/truncate-log.html?sfQueryTermInfo=1+file+log+truncat

DBCC SHRINKFILE(MyDatabase_Log, 1)
Go
BACKUP LOG MyDatabase WITH TRUNCATE_ONLY
Go
DBCC SHRINKFILE(MyDatabase_Log, 1)

It worked like magic! It seemed to change the initial size to 1 MB. I cannot change it from the 1 MB size, but my issue seems to be resolved for the most part.

Let it autogrow, and it will grow. You can limit its maximal size.

Thank you to both of you. dtodd gets a few points since his answer is probably another solution. Exaton helped me find the right search terms.
