Solidworks "load documents in memory only" doesn't work

Hello,

 

I'm using Solidworks connected with the 3Dexperience platform. I have a problem that whenever I open a large assembly, Solidworks opens multiple (tens) of referenced parts in separate windows which makes the session really inconvenient. This happens even if I have the option "load documents in memory only" ticked in Solidworks options. Does 3Dexperience and it's Solidworks launcher somehow ignore this? Is there a workaround?
