Product Page - Remove Shipping text below title

[GMK12]

Hello, 

I have a strange behavior on my product page which I cannot figure out how to solve it... 

In the English version everything looks as it should. It is about the text stating (Shipping included):

The strange behavior starts when I am switching to German:

Here it shows the standard Shopify text "shipping calculated at checkout" with a link to the Shipping policy... The strange thing is, that there is a condition in the code which checks the stock quantity of the product. Means as soon as there is stock value >0 it shows the correct text as well:

This is the part of the code mentioned above:

Any help is much appreciated.
