ELK plugin buggy sub-features

Hi all,

I am using ELK 2.2.2 for a real estate development potential study. I am using the OSM data compoenent and sorting the sub-features to show the uses in the area. However, after sorting the OSM components in accordance to the sub-features I noticed that after a while, all of them go back to °Building" feature type. Does anyone knows why this happens?
