Problem adding latitude and longitude to OUs


I am having issues adding latitude and longitude coordinates to OrgUnits through the maintenance application (I typed them in manually) . When I try to view the OrgUnits in the GIS app, I get an error message: No valid coordinates found.

I used an SQL view to pull the coordinates and found that they are presenting with quotations for example: [" -5.307033333","10.20165167 "] - I think this is causing the issue as other coordinates that were added previously do not have these quotation marks and they do display in the GIS. Any idea as to how I can resolve this?

Many thanks!
