Symmetrical circle effect

Hi hive mind. I have 5 robe megapointes on a mid truss #201-205, 4 on a back truss # 206-209 & 8 fixtures 2 on 4 truss towers spaced across a stage #211-217. I can produce the effect in the programmer. But after hitting “clear” and selecting the group and the effect from a palette th effect is totally different I.e has a different offset from centre? Any help would be appreciated legends.
