is it a normal behavior for 8.x ? I can't really upgrade now for compatibility issues but the users are not using the system because of it

I don't know, I suspect an error, but I can't help you because 8.2 is out of life.

Maybe another user who still uses 8.2 can help you out.

thanks! i know we should upgrade but it is not an option for now...
