RE: Things seem to be working well, except the on the entry form page, the category dropdown isn’t working, though it has categories to select.
There seems to be a conflict with the theme. They are, globally, enhancing select dropdowns instead of selectively enhancing select dropdowns used within their theme. This is breaking the enhanced select dropdown in Connections. Basically they both are thring to do their thing to the same input.
Here’s an article from the theme’s support pages which explains how to disable theirs:

After you follow their directions and clear any pages caches then, Form should work properly.
RE: can a visitor select more than 1 category when submitting a form?
Yes, the visitor will be able to choose more than one.
RE: It seems the Title of the category pages become a breadcrumb, instead of only showing the title of the category or the individual page.
Yes, this is applied for SEO purposes and can be disabled on the Connections : Settings admin page under the SEO tab. You’ll want to disable the Page Title option in the Page Display section.
Hope this helps!
