Hi,
Thanks for the details, it helps a lot! Unfortunately the screenshots didn’t come throught for some reason so I can only guess for now.
I tried the search as you suggested, selected “Άνω Τούμπα” as the filter value, and I get these results: https://i.imgur.com/HVBxtXo.png
I suspect the filter operator was set to the default “LIKE” instead of the “EXACTLY LIKE”, but now it seems to be all right.
About the layout, what exactly do you need to change?
