Relevant logs:

Not sure if there are logs that I should be including or not, and if so what? It seems to be a parsing issue.

No file, test, or entry point is identified in the issue. Reproduce the problem by logging in and checking the right-pane welcome message, then trace its rendering and verify that the customized message replaces the raw %s placeholder without adding the unprocessed text.
