This is a serious problem with Ninja form.
Based on the value of the number, the form is supposed to show different part of the form.
If number = 1
Show only the finals tep
If number = 2
Show the second step and final step
If number = 3
Show the second step, the third step and then finals tep
If number > 3
Show only finals tep
---> If we play a bit with the number and go back to number = 2, we can see that the conditional does not work anymore...
--> This problem seems to happen only when we use the "equals 2"
