The Gem Conference theme issues

1) How do I change the "Day 1" and "Day 2 " button background colors under the "conference schedule" heading? I would like it back to its original blue color. I'm not sure what changed the color. (see pic)

2) Is there a way to change the order of the blocks or sections that hold the event information under the conference schedule? I would like to move around the times of conference events without retyping all of them. My navigator has these sections under the pricing table so I can't see the individual sections. I'm not aware of how to do it (see pic)

3)How can I get rid of the gap that I have between the "Conference Schedule" heading and the event timeline listings? (See pic )

4) Can I add another email company provider aside from Mailchimp? I use Sendfox so I'd like to connect it to the subscribe section?

Thanks 

Thanks for the reply. 

I have attached screenshots with more details for questions 2 and 3. 

Question 2: I want to move around sections or event listings to accommodate scheduling changes. 
Question 3: I want to close the spacing gaps. I included your screenshot. 
Thanks again for your help 

Please let me know your thoughts so i can launch the website for my event. Thanks in advance 

Can anyone help me with this question about moving sections in blocks on The Gem Conference site? 

Thanks. It's a shame that the section is not easier to edit and move.
