i import base data and select demo version everything is fine till this point but when i want to select different version and come to the BASE IMPORT page, i am unable to select demo version and had to repeat the same process which causes duplicates the content. Even i refresh the page after import base data it did not allow me to select demo version. what is this problem. Why everytime i had to import base data to select demo version? I also watch your video regarding base import but there is no problem there. is there any bug in these updates?
