Check the header of the stored procedure - this is no version info in the header , just today's date - i think it was installed 2017 ( person who installed is no longer here)

sqlcmd -E -S $(ESCAPE_SQUOTE(SRVR)) -d master -Q "EXECUTE [dbo].[DatabaseBackup] @databases = 'USER_DATABASES', @Directory = N'E:\Backup', @BackupType = 'LOG', @verify = 'Y', @Cleanuptime =168, @Checksum = 'Y', @LogToTable = 'Y', @compress = 'Y'" -b

Could you check if the log backup is backed up?

You can see this in the dbo.CommandLog - table.
