Inconsistent notation for severity in output (sometimes uppercase, sometimes not)

[stefangreim]

• terrascan version: v1.8.1
• Operating System: ubuntu:latest (21.10) docker

Description

I store the output of a Terrascan scan in a file in order to perform further analyses. I noticed that the severity is available in different notations. I actually thought that this is always uppercase, but this is not the case. Is it possible to specify a consistent notation here?

What I Did

stefan@mine:~$ terrascan scan
