Numbered and Styled List Issues

Site is currently in maintenance mode. I’m having issues with numbered lists & styles using Powerkit. Hoping it’s not a theme compatibility issue. Numbered lists using either “pk-heading-numbered” (Formats-> Numbered headings-> Heading 2) look great in post editor but once saved as draft and in preview mode, the bubbled numbers are all the same. Also, whenever using “pk-list-styled” (Formats->Lists->Style) looks great in the editor, but the draft in preview mode shows double numbers in front of each list item. One bubbled and one numbered with decimal.
