When creating a record, the location box does not show your primary location. It instead shows the location of the last record your account was active for.
Have your users select the correct location from the drop down rather than choose the default location displayed.
This behaviour isn't a bug but instead is a temporary workaround. Donesafe is currently in the process of changing the way it handles locations and as a result, steps were taken to ensure that no users were locked out of locations that they should otherwise have access to. This required that auto location select needed to be deactivated for the time being. This functionality will be reactivated in future, but for the time being, manual location select is required.
