Can't select element on projects timeline

After you guys made these last updates to Express. I have now encounter several errors, but this is by far the worse.

I'm working on projects and I can't select elements on the projects timeline to shorten or enlarge its duration on it. 
Also, if I duplicate or delete a scene, it closes the timeline every time. So, every time I duplicate a scene I have to go back to the "Edit timeline" button to work on it, this is really frustating.
And finally, the way you moved the option to work on the projects pages to them bottom, is counter productive, because we no longer have the arrows on the sides to move from one page to another.

You guys are messing this platform big time and making me waste a lot of time in my business. I need help from you guys to have this fix ASAP. Your subscription isn't cheap, so we except for you to provide a way better service than this.
