I lost onscreen symbols

[Eleowen]

Hi there, hope you can tell me what's wrong.
I lost the locked encounter symbol and the broken encounter symbol, they won't show up anymore on the screen.
I tried to browse in the settings and there is nothing pointing to those symbols activation/deactivation.

I use a custom UI for the journal, the player window and the target window plus the Insomnia stat strip, all taken from this very site:

- simple player window by taco-man
- simple target window by taco-man
- quest-journal-mod by dogvomit

What could possibly cause my issue? Is the custom UI? (doesn't seem related, but may never know).

Thanks
