How to see the € price for the plugin Ebayomatic Post generator

Hello, the domain https://preisknecht.net gets articles from ebay with the ebayomatic post generator. I dont know what to do to see the normal price. At this time for example the price I see is 2400 euro but it cost 24 euro.  How can I change that? <b>Price Thousands Separator: ??? (is this the problem?
