Thank you for sharing the admin access.
I noticed that your view "Shiur Directory" is set to show posts from 3 post types:
1. Shiur Locations
2. Shiurim
3. People
But these post types, don't have any common address type custom field, which can be used for the view's distance-based search and to show map markers.
The "Shiur Locations" post type, has an address type custom field with slug "address".
The "People" post type, has an address type custom field with slug "shiur-contact-address".
And the "Shiurim" post type, doesn't have any address type custom field.
If you want the view to show posts from all these post types, along with showing their location markers on the map and also use distance-based search, then you'll need to make sure that these post types include an address type custom field with the same slug.
In case, you have some different requirements or expectations from these post types and the view, you're welcome to share the details and I'll be able to assist you accordingly.
To show the search fields and the submit button in a grid/columns, you can include a grid block and set it to show the number of desired columns for each search field. After that, you can drag and drop the search field blocks, into these grid columns. We have a detailed video tutorial on this topic at:

Your screenshot shows the normal block-based editor Gutenberg. You can learn more about this new default WordPress editor environment at:

Tip: If you'd like more width to be available for editing, you can set the maximum editor width to 100%.
