This is not a question we can answer, you have given us no information.
A link to a (probably) existing issue in a system we cannot see, with the statement "how to fill issue" is not even a question and there's nothing else to work with.
Ignoring the linked issue, to "fill an issue", click create and put in values for all the fields it asks you about. We can't tell you more than that.
