And we just noticed that your site shows the error “Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 786432 bytes) in /home/staydigital/public_html/olsa/wp-content/plugins/revslider/includes/googlefonts.php on line 2410”

It seems that your server has no enough memory limit and you need to increase it and try import data again.
