I reported this issue months ago along with a screenshot. The issue was also reported in JIRA. I have almost 6k downloads and users complain they cannot read the titles because the thread prefixes display in HTML instead of the way they were intended too.
vBulletin still has not addressed or fixed this in its latest release. I would like it fixed STAT. 8 months is too long to wait for something not to function as designed.
Here is a screenshot of the issue:
