It's not fully tested, but it seems to be working so far.

Replace function FCL.NewSkill in Combat Log Statistic.lua with:

function FCL.NewSkill(eventCode, Category, Type, MinXP, MaxXP, CurrentXP)
    local diff = 0
    local inLevel = 0
    local display = ""
 
    if (FCL.SkillsXP[Category][Type][3] >= CurrentXP) or (FCL.SkillsXP[Category][Type][3] == nil) then return end
    if (FCL.CText.Skills[Category][Type] == false) then return end
 
    diff = CurrentXP - FCL.SkillsXP[Category][Type][3]
    if FCL.SkillsXP[Category][Type][2] < CurrentXP then
        FCL.SkillsXP[Category][Type] = {GetSkillLineXPInfo(Category, Type)}
    else  
        FCL.SkillsXP[Category][Type][3] = CurrentXP
    end
    inLevel = FCL.SkillsXP[Category][Type][2] - FCL.SkillsXP[Category][Type][1] 
    percent = string.format( "%.2f" , ((CurrentXP - FCL.SkillsXP[Category][Type][1])/inLevel)*100)
    display = "|cc8ff3a+" .. diff .. " " .. FCL.SkillXPNames[Category][Type] ..  " (" .. percent .. "%)"
 
    if (FCL.CText.Time == true) then
        table.insert(FCL.CText.You, 1, "[" ..GetTimeString() .. "]" .. display)
    else    
        table.insert(FCL.CText.You, 1, display)
    end
 
    if FCL.CText.Chat == true then
        d(FCL.CText.You[1])
    end
 
    if FCL.Hiden == "You" then
        FCL.FadeTime = GetGameTimeMilliseconds()
        for i = 1, FCL.CText.MaxLines do
            if FCL.CText.You[FCL.Value + i] ~= nil then
                _G["CombatLog_Textbox"..i]:SetText(FCL.CText.You[FCL.Value + i])
            end
        end     
    end
 
end

And in function FCL.NewExp replace XP_REASON_FINESSE with PROGRESS_REASON_FINESSE.
