Shop balance not workingNot An Issue
I thought in the past the shop balance: true or false in the config it would balance the shop prices based on how much they were bought or sold?  Is that no longer a thing?  Can you also tell me what the Fixed: true or false right above cmd : null is for on the item config?
What do you mean? None of the other versions ever had this feature that you speak of?
I am almost positive it did a few years ago.  I remember having to turn something off to stop my prices from changing.  But I could be wrong.
If you happen to have a version somewhere that has it please send it. Because I have checked all versions on site and none of them have it. + That would need to be a global feature since it never had an individual data file for each player. 
Sorry, I dont.  Maybe it was another plugin because it says this one was released 2 years ago.

I hate to be the bringer of bad news, but that does not do what you think it does in any way, shape, or form.

The only thing that ever did do for, example:

Say I set up shop items with 0.06 pricing.
GUIShop would auto round the digit to a whole int value based on whether it was true or false nothing more nothing less.

There is the code from that version you can see for yourself.

        double GetBuyPrice(ItemData data)
        {
            if (!Balance || data.Fixed) return data.Buy;
            return Math.Round(data.Buy * GetFactor(data), 2);
        }

        double GetSellPrice(ItemData data)
        {
            if (!Balance || data.Fixed) return data.Sell;
            return Math.Round(data.Sell * GetFactor(data), 2);
        }

        double GetFactor(ItemData data)
        {
            if (data.Shortname == null) return 1;
            var itemname = data.Shortname;
            ulong buy;
            if (!buyed.TryGetValue(itemname, out buy))
                buy = 1;
            ulong sell;
            if (!selled.TryGetValue(itemname, out sell))
                sell = 1;
            return Math.Min(Math.Max(buy / (double)sell, .25), 4);
        }

This "Balance toggle" never needed to be a config option from the start ^
So all I did was remove it because GUIShop now handles all that logic in a much better and cleaner way.
