Hello, I've retopologized the head I sculpted and when I exported it back to Zbrush it seems like the model got double vertices/edges I guess. The edges look thick and when I try to hide loops using SelectLasso brush I have to click twice. I've tried to fix it with mesh > cleanup > merge by distance in Blender but it didn't help. Can you tell me how to delete those doubles please? Here are screenshots from Zbrush and Blender:

you also could have used "auto group" polygroup and split into groups to check
