Qt Creator picks up issues from build output that are not issues

The project that I am working on uses CMake+Ninja for building. It is mostly C++ but it has minor componts in other languages, including some node+typescript. In this context we have a build step that outputs the following to the log during a build

> license-checker --production --summary --onlyAllow "Apache-2.0;BSD;BSD-3-Clause;ISC;LGPL;MIT;Unlicense"

├─ MIT: 273
├─ ISC: 36
├─ BSD-3-Clause: 12
├─ Apache-2.0: 9
├─ (MIT OR Apache-2.0): 1
├─ AFLv2.1,BSD: 1
├─ (BSD-2-Clause OR MIT OR Apache-2.0): 1
├─ Unlicense: 1
├─ BSD-2-Clause: 1
└─ LGPL: 1

The problem is that Qt Creator picks some of these lines up and flag them as errors in the issue pane.

The flagged issues are:

• ├─ Apache-2.0
• ├─ (MIT OR Apache-2.0)
• ├─ AFLv2.1,BSD
• ├─ (BSD-2-Clause OR MIT OR Apache-2.0)

Curiously it is only picking up some of the lines from the output.
