Radiant Fire, bug. Sig. of Smoldering, bug.
I haven’t tested this, but you might want to post it in the bug forum so that it gets proper attention. If possible, you should also include a video recording of the bug or some very detailed information (i.e. with numbers and such).
I’m pretty certain that named condition duration (Burning, Bleeding) bonuses are not added to the Character sheet number at all. Your testing implies you actually tested it by hitting things with the burning, but if you haven’t, be sure that you account for that.
It is bugged. I tested it and had a thread on it earlier. Does not stack with sigil, cannot reach +100% burn time on enemies.

Of course, I did. The numbers are okay, unfortunately.

Well, anyway the problem is independent from the percentage, it looks just completely bugged to me.
By the way, did you post also on the Bug Forum, as other users are suggesting?
