Rotation in ArcGIS mode

Hi everyone .
I have used ArcGIS SDK in my project. but the rotation of an actor in Global mode (in ArcGIS) does not match to what I expect it.
here is an image(look at rotation value in edit mode and compare it with the attitude of cube, obviously it is NOT 0,0,0):

answer have been found!

EDITED:
that BP has a mistake!
it takes about a month to find it!!!
“add Arc GIS Location component” should not be added to tick event. in fact we should add it to begin play, then create a variable for it and set it.

finally it should be gotten in tick event.

ATENTION : IF you add it directly to tick event, it will decrease your fps gradually.
