Read rigts are added when entering a specific role inside the user management

Hi..

I have a online customer where after the 7.4 update there are some roles that when you enter the role in user management and clicks on the file cabinet tab.. then a popup is saying that the role read has been added to 2 file cabinets and if i look at the rights i can see that i is from the stanard profile.. 

But if i look at the standard profile in the file cabinet the Roles is not added to this profile..

What could cause this.. 

The Role is only assigned a index profile on the File cabinet giving restricted access to documents with a specific field value.. 

I have tested the same setup in my demo.. where this is not happening..
 

addon to the question.. why is the allow new entries not available when using index value profiles.. 
 

followup again..
the user cant update index data if this is not allowed..

And you cant set this if the index value profiles are used.. 

and if you create and custom profile.. then they can see all documents.. 

not that good
