netdata export function can't be found

Hello everyone ,I have installed the Netdata and accessed its web page o ,but i can’t find the export button, Can you help me take a look and see if there’s anything wrong ? Shouldn’t the export/import button be located at the top right corner of the page ?

This is the way ,i installed it :
wget -O /tmp/ && sh /tmp/

I have the same doubt. Were you able to find the cause for this?
