Elements disappeared from User Interface, help!

[Miguel_Gonzalez]

Usually when we open a new project at the left there is a lot of different options to drag into the canvas. Now I have a project with more than 6 screens and it does not show me all of the interface options as usually shows. What can I do?

Also in the Blocks section it does not show me the drag and drop options on any item.

Thanks in advance, anyone that can help me.

Check your blocks toolkit is set to All

Thank you so much!
It solved our problem
We have just to give it a couple of minutes to reflect the option in the other screens, although in Screen1 the change appear immediately.

Again thank you so much!
