Problem with smooth scrolling

Hello, I have set up a test-site with moesia.
I made a row with 2 columns (50% - 50%) with pagebuilder and added some css and widgets.
Now I want to use the smooth scrolling to anchor points in the two columns. Clicking on a link in the left column scrolls to the correct place in the right column. And here is the problem: Clicking on a link in the right column to scroll to an anchor point in the left column doesnt work. It only scrolls the right column a few pixels upwards.
Here is the CSS of the 2 columns:

left column:
position: fixed; top: 0; left: 0; bottom: 0; width: 50%; overflow: auto;

right column:
position: relative; top: 0; left: 50%; width: 50%;

If necessary I would prefer to send a link to the page by mail as the page is only work-in-progress by now.

Any idea why that isnt working?

After further testing I removed the smooth-scrolling from the file “scripts.js” and the anchor-links work like they should.

-> Is there a way to keep smooth scrolling and have the links work as they should?
