Accordian Shortcode behaves inconsistently

I am using the accordian shortcode on a page of mine, but it behaves inconsistently when there is a lot of content within the toggles.

Sometimes on page load specific accordian parts are expanded but the ‘+’ and ‘-‘ signs reflect incorrectly. It seems to be random as far as which parts it effects. When I reduce the amount of content I do not notice the same behavior. Note, I have all accordian shortcodes set to be collapsed by default.

Much appreciation for any help.
