I have 2 robots.txt !?

My site got two robots file at the same time…

https://www.worldstorehk.com/robots.txt is the default one, normal content.

https://worldstorehk.com/robots.txt is the one I don’t know where to edit it and this one ACTUALLY preventing the googlebot from crawling my site!

I tried to upload robots file and some plugin , but all affect on https://www.worldstorehk.com/robots.txt that one

I am so confused and upset that google blocked me and I cannot do anything ??

1) I don’t know why there exists two robots.txt … with and without www
2) I don’t know how to edit the file that without www

Anyone have the same problem and know what is going on?

Many Thanks!!!
