Solution
This is a known issue in AutoCAD. Please refer link below -
<https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Cannot-see-leader-arrowheads.html>
Leader arrowheads are not visible when the extension line of the leader is less than twice the size of the arrowhead.
This is the expected behavior of leader arrowheads.
To force arrowhead visibility, you must reduce the size of the arrowhead or increase the length of the leader extension line.
