I just checked and all the values in the timeline differ from the values in the Effect Controls.
Would not worry too much. Its cosmetic.
You could file a bug report though.
Are you sure the different scales between Effect Controls panel and timeline panel aren't intentional? It's not as if I can't work with this, I'm just wondering about the rationale, especially since the translation is non-trivial (0-30 vs. 0-100).
If you want to tweak the parameters stick to the ones in the Effect Controls.
That's what I've ended up doing
