Page ID issue

Hi

Hopefully I can receive some help.

With regards to the site I’m trying to set up.

When you visit my site: http://fifacoinreviews.com/
& click on one of the links it starts to load that page but instead of the correct extension it temporarily has the old page id. E.g.

It shows:
http://fifacoinreviews.com/?page_id=82

Then after a couple of seconds it changes to the correct address:
http://fifacoinreviews.com/fifacointrader-review/

I was wondering how to remove this annoyance and any help would be greatly appreciated 🙂

Apologies if not explained well.

Cheers
