[Help with uneccesary wall around a whole print?]

Hello i habe been using cura and other software for almost 3 years. Now i have just started getting an additional wall around some cylindrical items i print. This rises from the brim approx 10mmaway from the part and is one nozzle thickness. A complete waste of time and filament, please advise how to turn it off?

Many thanks
