Hi Enquiries17,
Thank you for getting in touch on the community page,
The reason why it is posting the letters lo is it is putting a county code in for you. The way in which to stop the lo appearing is, if you go into the cog wheel, account and setting and in the company section. In there you will be able to put the companies address in and the county you are in save it, it will stop showing the lo code or try selecting the drop down and selecting the blank section.
Let us know how you get on.
Thanks
