I am Unable to change my profile picture

Hi team,
Today I am adding my profile to my LISTLY account.

While trying to update my profile picture, I’ve failed and provided with a message as “restricted access”.

At present I have two lists, which was created, but that was duplicate one. While trying to remove duplicate one, again I was restricted to do so.

Can someone guide me to delete the duplicate list and update my profile pic as well.

Here is my profile LINK: https://list.ly/kavya-sahu/lists

Please help me out.
Thanks in Advance.
