Multiple iterations in Add / Delete programs


I have a strange issue. I had updated continuously the Scrivener Beta App. But I might have miss some of them. Well, It turns out, I have multiple numbers of Scrivener in the Add / Delete programs in the System Preference (cf image attachement).

The first three, the delete button is gray. The next three the delete button leads to the following error : “Windows cannot locate the uninstaller”.

I do not know what to do. Is there any one that can link me to a solution ?
