Hi Vikas,
Its something to do with listings not being in a category?
Although all my places are in a generic category as well as some in others it looks like when I open the places with the default icon there are no categories listed – then when I select a category the correct icon comes up.
I have tried to do a group selection and put these listings into a category but that doesn’t work, I would mention that all the places do however show up in the correct categories?
