I make a user then select specific role, but after save customer role automatically selected.
If the tick mark is removed, it comes back again after save.
please help me to solve it
Hmm 
@Arafat_Mehedi,
We did check on the latest versions 13 and 14. but we didn’t face issues like that.
If manually installed erpnext then first take a backup and then apply the below command.
bench update --reset
bench --site [sitename] migrate
bench --site [sitename] clear-cache
bench --site [sitename] clear-website-cache
Thank You!
