Duplicates in "Update site" list

I just checked my "Update Sites" list and saw that Mobile Joomla seems to add new entries every time I update. I now have about 12 entries for Mobile Joomla in that list, 6 for the pro version which I do not have and 6 which have a blank title but I assume they are for the basic version. Can you please fix this, that no more entries are added.
Also, how can I delete these duplicate entries? I seem to be only able to "disable" them but I can not delete them...

Hi oliverjoom,

There have been lots of updates on our new version MJ 2.x for bug fixes and new features.

Can you send us more details about this issue to our email support​@​mobilejoomla.com
