I'm using the Keynote template.

I have three issues

1. I get Call to undefined method Joomla\CMS\Pagination\Pagination::get() on the speaker page on the frontend
2. I cannot reorder the speakers on the backend. When I drag the reorder holder the speaker been dragged moves around but is not able to be placed in another location
3. I cannot find where to enter description for the sessions. I initially tried to use the demo content but noticed there were extra descriptions in the sessions on the frontend I could not change, I then created new sessions but no description textbox too
4. I cannot add sessions without a speaker attached. I see the demo has sessions with no speaker. How do I achieve this becase there are breaks and Lunch e.t.c. that speakers do not apply to and I need to add those
5. How can I display the speaker designation directly in the schedule? 6.How can I get the speaker images on the schedule to link to their profiles?
