>Thanks, I adjusted the Autogrowth by 1 MB. Then, I tried to set the initial size to 1 MB instead of 352. But, that value does not get saved. Even if I save it with 1, whenever I come back to that option, it says 352. On disk, this is the size of the file. Between those steps, I tried a shrink file but that doesn't change anything.

Try with SSMS:
Right Click on DB
Tasks->Shrink->Files
In the form choose "File type: LOG"
From option group "Reorganize pages before ...."
and then set File size to 0 (Zero) MB

Script:

USE [YourDBName]
GO
DBCC SHRINKFILE (N'NameOfTheLogFileHere' , 0)
GO

If both didn't help, then try to see why.
In your previous thread, the error have the info:

SELECT Name, log_reuse_wait_desc FROM sys.databases
WHERE Name = 'YourDBName'
