Thanks for the hint.
I fixed both player and group window. Now all dots shows as they should. Plus I added Curse dot... ofc click to cure works as well.
Only Full Window variant was modified. And I had to remove F1-F6 icons to get some space for 5th dot effect.
As I was playing with UI files, I added missing information to Persona Window -> Spell effects section (dmg and heal mods, casting speed/reuse/recovery).
Have fun - everything should work (I hope).
