Scaling/effect values of items don't update when you change the configured defaults? + Better UI?

[Darkmega18]

I've apparently changed and saved mysterious vials regen rate to higher, to make it meet the one from classic items then disabled classic item's vial, since I had this mod first. However when I changed the values, ingame it doesn't become any different, still says 0.8 instead of the 1.2 it was changed to.

is there anything that can be done for this?

also, potentially related, can there be compatibility for better UI mod and it's advanced item descriptions etc?
