If you do not see imported bookings, from external .ics feed, then please recheck these points:
1) Please be sure that in your ".ics" feed exist some events, relative to current or future days.
You can download this .ics feed and open in notepad and check your events there.
2) If events was imported before, then such events will not be imported again.
Booking Calendar can import the events from external sources only once (if have not been activated options "Force import" or "Trash all imported bookings before new import" at the Booking > Settings > Sync > "General" page in Advanced section).
May be you are having these event(s) in the Trash or such event(s) was imported into not exist booking resource.
In this case, you need to delete such previously imported bookings (that was imported into non exist booking resource), and then try to import these bookings once again by using correct shortcode.

3.3) Open "oPlugins Panel" > "Manage .ics" page, then paste URL of your .ics feed (that you need to check), and click on "Show Events (.ics)" button.

You can click on booking ID link to open the Booking Listing page with this specific booking and see, details of this booking. Check the booking resource, where this booking saved.
4) If the booking was not imported, then please recheck parameters of import shortcode.
