How to make a proper table script that rules out types based on input?

What I am trying to recreate is the journal from Phasmophobia on steam, basically, you have 8 evidence, and when you get one, some of the names that aren't possible gets set to 0.8 transparency, eventually with 3 evidence it will tell you the exact type, however since I am new to scripting, I have a few issues. The main one being that when you remove an evidence, some of the types gets overwritten and the journal ends up telling you the wrong thing, as you can see in the link below. The second issue is that the script is written in the worst way possible and I need help with optimisation.

And heres the line of code that is used for every single evidence

script.Parent.CONCLUSION.EMF.MouseButton1Click:Connect(function()
    if script.Parent.CONCLUSION.EMF.ImageTransparency == 0 then
        script.Parent.CONCLUSION.EMF.ImageTransparency = 1
        local all_evidence = script.Parent.CONCLUSION:GetChildren()
        for _i,v in pairs(all_evidence) do
            if v.ClassName == "Frame" then
                local evidence = v:FindFirstChild("EMF")
                if not evidence then
                    v.NAME.TextTransparency = 0
                end
            end
        end
    elseif script.Parent.CONCLUSION.EMF.ImageTransparency == 1 then
        script.Parent.CONCLUSION.EMF.ImageTransparency = 0
        local all_evidence = script.Parent.CONCLUSION:GetChildren()
        for _i,v in pairs(all_evidence) do
            if v.ClassName == "Frame" then
                local evidence = v:FindFirstChild("EMF")
                if not evidence then
                    v.NAME.TextTransparency = 0.8
                end
            end
        end
    end
end)

This line of code is copy and pasted for all 8 evidence, and that is the issue, but I do not know how to write it in any other way...

Thanks to everyone that helps in advance.
