Beaver Builder Tool Bar Missing

The beaver builder top tool bar does not show up on several of my individual pages when I engage beaver builder from my dashboard. Sometimes it shows up the first time and then it disappears and I can’t get it back on that page. I click on pages > (select a page) > then click the button “launch beaver builder”. Then it opens the individual page for editing with NO beaver builder tools or buttons. It is impossible to edit my page without reverting to the standard editor which kills the original design of the site. I’ve cleared the cache and that didn’t help. I’ve checked all my updates and that didn’t help. I’ve logged out and back in and that didn’t help.
