Issue: Spoiler and [-] tags do not show up

I don't know if this is just happening to me for some reason or it has been mentioned before; when I choose "Standard Editor - Extra formatting controls" and try to use Spoiler or [-] in my posts they turn into MENTION. When I choose "Enhanced Interface - Full WYSIWYG Editing" there is not a problem. Thank you for your assistance.

Here is how it happens if I couldn't be clear with my explanation:
