You may have not exported the entire piece, see if selecting everything before exporting will fix it (I don't use FreeCAD so IDK for sure)

Thank you guys for your response and even your willingness to help! I actually just switched to Fusion 360 and found it way better than FreeCAD, so I was able to fix the issue. Thank you anyway guys!
