Hey Jacob,
Thanks for reaching out to us!
The original issue you’re describing sounds like it is most likely a javascript error on the site. Do you have a link to your site where you’re experiencing this issue so we can test a little further?
Also, I’m not sure I’m following the last part of the message, “respectively target the calendar page with the date (the week the date is included) being pre-selected”. Are you wanting to link to a specific date on the full calendar? If so, you can link to the calendar with an additional “/2015-11-11/” for the date that you would like displayed.
Let me know if this helps.
Thanks!
