Structure has no member with intellisense

Hi !
I encounter a problem with Intellisense (VS2013) showing the first member of all my custom USTRUCTs as non existent. Next members are ok tho.
The project compiles but the editor seems to loose its mind.

I have several friends that experience this same problem on 4.6.1.
Is there any way to resolve these errors ?

Thanks!
