After Update to 2.0.14: Product price shows "+0" self provided rows

[Chigolo]

Hey,
I've updated Vm from 2.0.10 to 2.0.14, Joomla version is 2.5.8. Now it shows me "+0" in the self provided rows, even when I delete the "0". It's only a "beuty-fault" but it worked in 2.0.10. So where can I deactivate it?

Here is an example:https://www.beast-supplements.de/shop/aminosaeuren/aminosaeuren-liquid/amino-liquid-1l-detail.html
