Is it still as bad? Doesn't look like you still have duplicated tags/prefixes anymore, maybe just not shown in that screenshot though. Your problem is capitalization--prefixes are case sensitive now. They may not have been on 3.x. That means you need to either convert everything to lowercase (there's an AT&P tool to do that in one swoop), or manually fix your existing tags to have the right capitalization in the Manage Tags section. "et application" and "ET Application" are not the same thing. If you change "et application" to be capitalized, it'll style correctly.
I'll look into that, thanks. What version are you running? I fixed a number of such issues in recent releases, maybe the mass-add tool escaped me though.
Another workaround would be to use the full name, and disable the 'include title in formatted prefix' setting, entering whatever text in the prefix/suffix fields manually.
This used to be a feature way back on like IPB 3.1. Immensely invasive (required overriding a swathe of core code, was always causing problems), and highly prone to performance problems. I wish it could be done easily.
Thanks for all the suggestions.
Are you running the latest version? Just making sure before I investigate. I addressed issues like this last release (I think).
Yes, that is correct.
