There is an issue with the lenght of the fields
I would apply some CSS to your template custom.css file:
#pac-input, #marker-search {
padding: 0 20px;
width: 300px;
}
Then move the marker search to TOP-CENTER position.
There is indeed an issue with the marker search not working.
It is finding things but the results keep the display:none css and wrong width
There is a javascript error on the page, showing in the browser console.
Uncaught TypeError: Cannot read property 'length' of undefined

It may be related to the issue. I don't know if it is conflicting or if it was there before and prevents the search to show correctly.
Disable the module to see if the error persists or not. Let me know. You can also email me backend access if you want me to have a look.
