1600 and 2600 series aps no heatmap on cisco prime 1.4.0.45

Question

after plotting 1600 series and 2600 series aps on the respective uploaded maps, there's NO heatmap coming out. 
setup composed of:
1600 series aps
2600 series aps
wlc running HA (7.4.121.0)
cisco prime 1.4.0.45
i noticed some errors from prime:
error 1: Exception while computing Coverage Heatmap. Message: COMMON-1 Try Recompute RF Prediction - this error message shows after positioning the aps on the map and clicking save button. it took sometime to display then this error message shows. 
error 2: Error in Recompute RF Prediction: SyntaxError:syntax error - this error shows after running recompute rf prediction option
i tried 802.11a/n and 802.11b/g/n protocols but still no heatmap. i tried unselecting ap heatmaps option and select it again but still no heatmap.
anybody have an idea what is going on? tia

Hi,
Try removing both APs from the map and saving. Next, go back into the map an assign the APs. If they still do not map then I would look at the traps on the controller and make sure that the AP is fine. I would also look at performing an on demand refresh from the controller to the WCS. You can do this from the management page in WCS.
