The multileader arrow is not showing even if the number is increased (ie from "4" to "10") in the multileader dialog box or under the properties when modified.
Is your multileader annotative? If so, 4 to 10" is way too big. The arrows would be so large that they would not be drawn in a typical leader length. Arrows should be set between 3/32" and 3/16" if annotatively scaled. Check your annotation scale as well.
