Why are two identical strings being detected as different?

Let's image partTouching value is "Flashlight". Now look at line 15. The first variable of the list is also "Flashlight". So, when I'm comparing the two, for some reason, roblox decides that "Flaslight" and "Flashlight" are different things. Am I comparing the wrong thing? Help, please.

local detector = script.Parent
local itemList = require(game.ServerScriptService:WaitForChild("Modules").ShopItems)
local itemValue = script.Parent.Parent.Item
local debounce = false


detector.Touched:Connect(function(partTouching)
    if debounce == false then
        tostring(partTouching)
        local debounce = true
        for i = 1, #itemList do
            print(partTouching)
            print(itemList[i])
            --print("something is touching")
            if partTouching == itemList[i] then
                if itemValue.Value == "" then
                    itemValue.Value = partTouching
                end
            end
        end
        detector.TouchEnded:Wait()
        local debounce = false
        itemValue.Value = ""
    end
end)
