700i. In IR contacts adds international code twice before the phone number

Hi. On my montana 700i under IR contacts the international code is duplicated eg: +6161408556xxx.

I have loged in to the explore website, under my account and the phone number is correct.eg:+61408556xxx.

On garmin explore app also the phone number is correct. When i do the sync between explore app and montana 700i everyting syncs ok but my contact details remain the same unchanged. Hope you can help .

Thanks
