This is the left-over work from the previous freelancer. I did not notice when I signed off the work that the freelancer has done the annoying shortcut , using the same layers for the multiple objects. The requirement for the work is:
(1) Separate layer for separate objects.
(2) Give a identifiable name to the layer, possibly group the layers if you can.
I will not be quick this time to sign off the work and give 5 stars until we have verified everything. This means your persistent push for payment and request for 5 star will not work!
