Before guessing too much:
- which Kicad version do you have in use?
- which symbol exactly do you use? (from standard kicad library? or somewhere downloaded?)
generic advice regarding this forum: try to read New Member Information and follow the instructions. This enables you to get the next “basic” user level in this forum. With that user level you are allowed to attach a example project (use “File–>Archive project” from the kicad main project manager). With such a example project it’s easier for us to help you.
