Section links drives the bottom of the viewport to the top of the section

For some reason, the section links on my page are now making the viewport’s bottom go to the section, instead of the viewport’s top matching the section’s top.

In the example, when you click “What I Do”, it should link you to the purple section. Instead, it puts the viewport just on top of it.

Is this a stupid issue? Is there an option t switch it back?
