Fakku Store's Search Button is Broken

As the title states, the Search button on the Fakku Store doesn't actually do anything when clicked, although pressing enter works properly. I tried it on a couple of different browsers (chrome, edge) with the same result.
There's also a different problem on the main website with the page buttons at the bottom. The 'First' button doesn't take you to the first page; it just takes you to the top of the current page.

Works on my side. Maybe they fixed it.

I tested clicking the Search button when trying for a result on the Store page, and it doesn't work for me either.

Pressing Enter still works, however.
