Checking...this looks simple enough.

Paste this code over the top of the code in the HideBuffs.lua

UIParent:SetScript("OnUpdate", function()
    if TargetFrame:IsShown() then
        for i=1, MAX_TARGET_BUFFS do
            local frame = _G["TargetFrameBuff"..i]
            if frame ~= nil then frame:Hide() end
        end
 
        for i=1, MAX_TARGET_DEBUFFS do
            local frame = _G["TargetFrameDebuff"..i]
            if frame ~= nil then frame:Hide() end
        end
    end
 
    if FocusFrame:IsShown() then
        numDebuffs = 0
        for i=1, MAX_TARGET_BUFFS do
            local frame = _G["FocusFrameBuff"..i]
            if frame ~= nil then frame:Hide() end
        end
        for i=1, MAX_TARGET_DEBUFFS do
            local frame = _G["FocusFrameDebuff"..i]
            if frame ~= nil then frame:Hide() end
        end 
    end
end)
