Jira Board Workflow change

Question

Hi

I have an old project, what an old made by a colleague.

In this project Now name it as A.  I had this Workflow option, where I can toggle the Board based on which tasks I want to see in which Workflow.

I have made 1 new project name it as B, with 3 workflows this button does not appear in board menu.

I created a task with each of these Workflow types.

Where can I set it to display this?

And in the new project B, all tasks disappear from the board after I create them in a few seconds.

How can i solve it?

I solve it!!

I do the Switch Scheme to mine, what i already created. But the system was set to default Jira Workflow.

Added again the Workflows, and now it's working. 
I have the button, i see tasks on board.

The  solution was simple. Reset your workflow and scheme. Add again what you want. 
it will work.
