Just wanted to post a follow up here. In a previous post here: https://theeventscalendar.com/support/forums/topic/conflict-with-woocommerce-subscriptions/
Barry posted a gist to solve the drop down menus always staying open. I believe this was tracked to a woocommerce admin styles conflict with subscriptions.
His code handles the post type tribe_events, but venues is also a post type that needs to be covered, so I added that to his original code with another gist that fixes the conflict for event post type, settings pages, AND venues. No heavy lifting here, all credit goes to barry. thanks for the original solution.
Gist here: https://gist.github.com/orgspring/8206008
Hope it helps.
