There are many reasons for the step doesn't appear:
First, you should make sure that you have chosen the right actions to make that step appear.

Incorrect Element Selection
Secondly, the element could not be detected because it was incorrectly selected during the guide creation.
If this was the case you can just Re-select the correct element. There are also some elements that cannot be selected automatically by Point & Click. For these elements, you can associate a step through the HTML Selector.

Guide Started on a wrong page
Apart from the first step of a guide, which, by default, redirects you to the guide's start page, the following steps won’t start if you are not on the correct page for those steps. You will need to create a "Click" action to redirect users to another page.
If the first step is common to various pages or is a Pop-up, even though you are in fact able to start the guide on the page you are right away, the guide won’t be able then to conjure the next step because this step’s element is in another page.
You should make the first step of that guide start only in that one specific page where the rest of the guide will then unfold. To see how to do this you can check our article here.
Step Element Hidden
If one step element is hidden or it's not on the correct page, this is enough to make the guide fail and cause the other steps to disappear.
Some elements are always hidden until the user performs an action, for example, a demo calendar.
Select the option "On-Hide" in the Actions dashboard of that specific step so the guide can function without interruptions.
Lastly but not least, if it happens that your website is having problems, such as slow site loading, the guide will also be affected and it might break down. This results in some steps not appearing as the guide can’t continue/start.
