Hi there, Yadu. Version 1.8.1 fixes bugs related to sorting and positioning for the different tile types. It's a long story of the differences between tile placement in Tiled vs. Unity and the coordinate systems they use but, yes, I can how this is causing an issue for you.
I think the best option for you would be to have your own CellToWorld function that modifies pos.y (decrements by one) or change your placement code to subtract an additional cellSize.y from p.y.
If you want to discuss this more then open a bug on github and we can see if there's better options.
