Error in top bar (phone number)

Hello,
the top bar seams to produce an error with the entered phone number in the following format “+4412345….”. It is displayed correctly, but when clicked on a mobile device, which should automatically dial the phone number, some “htt code” or equivalent digits are transmitted, so that the entered phone number cannot be dialed.
I tried some customs CSS, but was unable to rectify the error.
Please have a look on our website and try it yourself.
I hope it is an easy fix.

Thank you
Joey
