Property Notes exists twice in Standard Class

I just came across an Error, when I wanted to create a Standard Object via SMlets.
The error is: "Item has already been added. Key in dictionary: 'Notes' Key being added: 'Notes'"
The standard is created still. After some testing and trying to set the Notes value as well, I checked the Standard Class inside the Entity Explorer. There I saw, that the standard class has 2 properties with the same name "Notes". One is from the configitem class, and one is from the Standard class - both have different property Ids and property types as well.
Is it somehow possible to remove that double poperty in a new version? Or will this lead to errors in the DB and/or all Request Offerings, which contain the standard class in it?
