Plusnet Webmail Incoming Mail Listed in random date and time order.

[#1]

I use Windows Live Mail 2011 as my e-mail client.
My settings allow me to save my e-mails in Plusnet Webmail until I delete them  - I do that every five days or so.
I would like to know why my list of incoming e-mails are presented on Plusnet Webmail in a completely random date and time order.
Is there anything I can do to change this? .
I shall be grateful for any suggestions.

Click any column heading to sort by that column - a second click reverses the sort.
Or click the icon to the left of the headings to get the List Options which give more options.

Hello jelv,
Thank you very much for your reply.  I have done what you have suggested - date and time order all ok now.
