Several glitches

I am having lots of problems with this theme. I have purchased many Catch themes and typically like them but have never had this many issues. Not sure why. I will list them below. I really needed to work behind the scenes on this site but will take down the splash site so you can see it. http://www.chefaarondeal.com 1 Fonts will not change in customizer. If they do, it is rarely the fonts I have selected. 2 Some chagnes take a while to display. This doesnt seem to bea a browser issues as it happens on multiple achines. Why is that? 3 Featured Slider text in particular take a long time to "show up" on the site once entered. I'd rather just removed the text shadobox on this section altogether,; is this not an option? (I am using featured images for the slider) 4 Editing pages is cumbersome because when logged in, there is never a pencil/edit icon. That is fine except that you can no longer edit through the admin menu a the top, so I have to go ALL the way back through the dashboard to navigate to the page I want to edit. 5 The theme does not update through the wordpress admin panel (says "An error occurred while updating Helena Pro: Update package not available.") 6 Catch updater will also not update through the admin panel. (says "The package could not be installed. The theme is missing the style.css stylesheet.")
