For every person, who doesn't know what happened, there was a bug in version 1.3. If you tried to change the ShopType, instead of switching from [AdminBuy/AdminSell] to [AdminSell/AdminBuy] it changed to [Buy/Sell], this is fixed now

Für jeden, der es noch nicht weiß, es gab einen Fehler in der Version 1.3, wenn man bei einem AdminShop den ShopTypen im Inventar gewechselt hat, ist es zu [Buy/Sell] geworden anstatt [AdminBuy/AdminSell]. Dieser Bug ist jetzt gefixt

Plugin ignored the count of the items, that should be selled, this is fixed now. If you have a bug, please report it

I forgot to add some messages to the language configurations, now all messages in the plugin are editable

I forgot to add the language settings .___.
