It appears to be a theme specific issue rather than the plugin itself. Just tried with another theme, and the HTML formatting remains intact.
In my situation I found a
list-style: none;
in the theme style sheet which caused the issue.
It’s a major pain.
I’ve checked the code, can’t see why this is happening. It does’t happen on the Job List page, just the Job Details page.
If I figure it out, I’ll post the fix (since the developer seems to have lost interest in this plugin)
