I Update My Working Hours, Calendar Doesn't Change

Two Issues:

1) I have changed the Working Hours in the settings of Appointments+ to be open on Saturday and Sunday, but the calendar displayed via shortcode continues to show Sat/Sun as unavailable.

2) The shortcodes section of the plugin says I can use alternate 'h' tags to change the formatting of the titles, but when I do that the title just show the < h1 > tag around the text.
